More Details on Our Top Picks
Levoit Air Purifier for Home Pets Hair Allergens in Bedroom Quiet Purifier
This Levoit Core 300-P stands out for its reliable HEPA-grade filtration that captures 99.97% of airborne particles, including pet dander, pollen, and dust, making it a top choice for allergy sufferers. Compared with larger units like the MOOKA or the large-room models, it excels in quiet operation and easy use, perfect for bedrooms and small offices. Its main tradeoff is that it’s limited to smaller spaces and requires regular filter changes every 6-8 months, which can add ongoing costs. Still, its combination of safety certifications, sleep mode, and user-friendly features make it a balanced pick for those prioritizing quiet, effective air cleaning in intimate spaces.
Pros:- Effective HEPA-grade filtration capturing fine particles and allergens
- Quiet operation with Sleep Mode and near-silent noise levels
- Certified safe for home use with multiple safety certifications
Cons:- Only suitable for use in the United States due to voltage requirements
- Requires official replacement filters for optimal performance
Best for: Pet owners and allergy sufferers needing a quiet, reliable purifier for bedrooms or small rooms
Not ideal for: Large open-plan spaces or users seeking smart home integration, as it lacks advanced connectivity features
- Power:56W
- CADR:143 CFM (smoke), 153 CFM (dust), 167 CFM (pollen)
- Coverage Area:222 ft²
- Filtration Efficiency:99.97% for 0.1-0.3μm particles

Our verdict“This model is ideal for individuals needing a dependable, quiet purifier in small domestic spaces, especially bedrooms.”
Air Purifier for Large Rooms Up to 2400 sq ft with True HEPA Filter
This large-capacity purifier is designed for spaces up to 2400 sq ft, offering a dual-power filtration system that captures 99.97% of airborne particles. Unlike the smaller Levoit Core 300-P, it includes smart features like real-time air quality monitoring, auto mode, and aromatherapy, making it suitable for open-concept living areas or large offices. However, it relies on official ECOSELF replacement filters, which can be more costly and less readily available, and its fan speed options are not fully detailed, possibly limiting customization. For users needing frequent, high-capacity air cleaning with tech integration, this model provides a compelling option.
Pros:- Effective for large rooms up to 2400 sq ft
- Captures 99.97% of airborne particles with true HEPA
- Real-time air quality monitoring and smart auto mode
Cons:- Requires official ECOSELF replacement filters, which may be costly
- Limited details on fan speed options and control flexibility
Best for: Homeowners with large living rooms or commercial spaces requiring continuous, high-capacity air purification
Not ideal for: Small bedrooms or users on a tight budget, due to higher ongoing filter costs and potential complexity
- Coverage Area:2400 sq ft
- Filtration:True HEPA
- Noise Level:22dB
- Features:PM 2.5 display, infrared sensor, sleep mode, aromatherapy, auto mode, timer, lock controls
- Certifications:ETL, FCC, EPA, CARB, DOE
Our verdict“This purifier suits large spaces where integrated air quality tracking and high-capacity filtration are priorities, though at a higher cost and complexity.”
Levoit Air Purifier for Bedroom and Home
Compared to the larger, feature-rich models like the 360° airflow purifier, this Levoit offers a more compact form suitable for small to medium rooms, with effective removal of pollutants, pet dander, and odors. Its quiet operation and sleep mode make it ideal for bedrooms or offices, but it’s limited in coverage area and power—best suited for spaces under 200 sq ft. Its lack of detailed filter replacement info and absence of smart features mean it’s a straightforward, no-fuss option for smaller environments, trading off some advanced functionalities for simplicity.
Pros:- Certified for reliable air cleaning performance
- Effective at removing pollutants, pet dander, and odors
- Quiet operation with sleep mode and aromatherapy options
Cons:- Limited to small spaces due to size and power
- No detailed filter replacement information provided
Best for: Individuals seeking an effective, quiet purifier for small bedrooms or personal offices
Not ideal for: Large open spaces or those wanting smart home connectivity and detailed monitoring
- Power Input:100-240V, 50/60Hz
- Rated Power:7W
- Noise Level:27-45dB
- Dimensions:6.5 × 6.5 × 10.4 inches
Our verdict“This purifier is well-suited for small rooms where simplicity and quiet operation are valued over smart features or large coverage.”
Air Purifier for Large Room, Cleans 2,400 ft² in 30 Minutes, 3-Stage True HEPA, 360° Airflow, Touch Display, Real-Time PM2.5 Display, Ultra-Quiet Sleep Mode
This model is designed for quick, large-area purification, capable of cleaning 2,400 sq ft in just 30 minutes thanks to its 3-stage HEPA system and 360° airflow. Unlike the smaller Levoit, it offers a user-friendly touch display, real-time PM2.5 monitoring, and ultra-quiet sleep mode, making it ideal for large bedrooms or open-plan living spaces. Its performance comes with the caveat that filter replacements every 3-6 months can add to maintenance costs, and it may lack some smart home features present in more advanced units. For users prioritizing rapid, extensive air cleaning with straightforward controls, this model makes a strong case.
Pros:- Covers large areas up to 2,400 sq ft quickly
- Real-time PM2.5 monitoring with a clear touch display
- Ultra-quiet sleep mode for undisturbed rest
Cons:- Filter replacement every 3-6 months can be costly
- Performance may decline with high pet hair or dust loads

- Coverage Area:2,400 sq ft
- Filtration Stages:3-stage HEPA
- Noise Level:20dB in sleep mode
- Display:Touch control panel
- Air Quality Monitoring:PM2.5 sensor with real-time display
- Auto Mode:Yes
- Filter Replacement Interval:Every 3-6 months
Our verdict“This large-room purifier suits those who need rapid, high-capacity cleaning with simple controls and quiet operation, at the expense of higher maintenance costs.”
MOOKA Air Purifier for Home and Large Rooms up to 2200 ft², HEPA Filter, White
The MOOKA purifier is tailored for large spaces up to 2200 sq ft, with a multi-sided air intake and a 3-stage HEPA filtration that effectively removes pet dander, smoke, and odors. Compared to the Levoit models, it offers smart sensors for real-time air quality tracking and auto mode, making it suitable for tech-savvy users who want an effortless experience. Its quieter operation in sleep mode and aromatherapy options add to its appeal, though specific dimensions and weight are not provided, which could be a concern for portability or placement flexibility. It’s a well-rounded choice for large rooms with a focus on smart tech and continuous air quality management.
Pros:- Large coverage area up to 2200 sq ft
- Quiet operation in sleep mode
- Smart sensors and auto mode for effortless air quality control
Cons:- No specific dimensions or weight info provided

- Power Consumption:0.63 kWh per 24 hours at max speed

Our verdict“This smart-capable purifier is ideal for those who prioritize continuous air quality management in large spaces, accepting some unknowns in portability.”
Levoit Smart Air Purifier for Large Rooms up to 1875 sq ft, Vital 200S-P
The Levoit Vital 200S-P stands out for its impressive coverage of up to 1875 square feet, making it ideal for large living rooms or basements. Compared with smaller units like the VOOPNU, it offers a far wider reach, but this comes with increased noise at higher speeds. Its AHAM certification confirms reliable performance, and it effectively tackles allergens, smoke, and odors—perfect for allergy sufferers and pet households. However, its complex filter options and potential noise at maximum fan speed may challenge users seeking quiet or straightforward operation. This model is best suited for homeowners who prioritize large-area coverage and allergen removal over ultra-quiet operation or simple filters.
Pros:- Extensive coverage area suitable for large rooms
- Certified by AHAM for safety and performance
- Highly effective at removing allergens, smoke, and odors
- Designed specifically for allergy and pet households
Cons:- No pricing details, which may influence purchase decisions
- Filter complexity could confuse some users
Best for: Large households needing comprehensive allergen and smoke removal in big spaces
Not ideal for: Small apartments or users sensitive to noise, as it can be loud at higher speeds
- Coverage Area:1875 sq ft
- CADR Ratings:Smoke: 250 CFM, Dust: 254 CFM, Pollen: 289 CFM
- Certifications:AHAM Verified
- Suitable For:Large rooms, living rooms, bedrooms, basements
- Filtration:Multiple replaceable filters for allergens, toxins, smoke, pet hair, and odors
Our verdict“This pick makes the most sense for large space owners who need powerful allergen and smoke filtration despite potential noise and filter setup complexity.”
Levoit Air Purifier for Home Pets Bedroom Dorm Room Washable Pre-Filter
The Levoit Vital 100S-P offers a balanced mix of performance and quietness, making it ideal for bedrooms, dorms, or pet areas up to 1,073 square feet. Its washable pre-filter reduces ongoing costs, a feature that differentiates it from models like the VOOPNU, which requires more frequent filter replacements. The HEPA-grade filtration captures 99.97% of tiny particles, and its noise level drops to as low as 25dB in Sleep Mode, supporting undisturbed rest. While setup involves multiple filter options, which could be confusing for some, the overall ease of use and effective pet allergen removal make it a smart choice for pet owners or light allergen sufferers. This purifier is best suited for those seeking quiet, cost-effective air cleaning in medium-sized rooms, especially with pets.
Pros:- Effective for rooms up to 1,073 sq ft
- Washable pre-filter reduces long-term costs
- Quiet operation in Sleep Mode
- Multiple filters tailored for pet and allergen removal
Cons:- Requires official Levoit filters for best performance
- Setup can be complex due to multiple filter choices
Best for: Pet owners needing quiet, effective air cleaning in bedrooms or small apartments

- Pre-Filter:Washable
- Noise Level:as low as 25dB in Sleep Mode

Our verdict“This model suits pet owners prioritizing quiet, cost-efficient air purification in medium-sized spaces, despite some setup complexity.”
FreAire HEPA Air Purifier for Large Rooms up to 3,850 sq ft with Air Quality Monitor, Sleep Mode, Pet Mode, and App Control
The FreAire HEPA Air Purifier makes a compelling case for large-area coverage up to 3,850 square feet, surpassing models like the Levoit 200S-P in scale. Its smart app control and air quality monitor introduce a level of convenience not found in simpler units, while modes like Sleep and Pet ensure tailored performance for different environments. Its quiet operation at 20dB in Sleep Mode supports night-time use, and the washable pre-filter keeps maintenance straightforward. However, the need for regular filter replacement every 3-6 months, along with its higher price point, may deter budget-conscious buyers. Compared to smaller units, this model is better suited for large, open-plan homes or commercial spaces where smart features and large capacity outweigh the cost and setup effort.
Pros:- Enormous coverage area suitable for big rooms and open spaces
- Smart app control and real-time air quality monitoring
- Quiet operation, ideal for bedrooms and nurseries
- Reusable pre-filter for easier maintenance
Cons:- Requires frequent filter replacement every 3-6 months

Its 360° filtration system and 99.97% removal of airborne pollutants ensure reliable air quality improvements, rivaling larger units like the Levoit 100S-P but in a smaller footprint. Its operation at just 22dB is notably quiet, ideal for bedrooms or workspaces. The inclusion of an essential oil tray adds a touch of relaxation, and controls are straightforward, appealing to users who want simple, effective air cleaning. The main tradeoff involves the need for continuous operation and reliance on official filters, which could add ongoing costs. This pick makes the most sense for individuals seeking a compact, quiet purifier for medium-sized rooms without fuss.
Pros:- Covers up to 1076 sq ft efficiently
- Quiet operation at 22dB suitable for bedrooms
- Includes aromatherapy tray for relaxation
- Easy-to-use controls

The VEWIOR 2 Pack offers a versatile, cost-effective solution for maintaining clean air across larger spaces up to 1200 square feet. Its 360° intake and 3-stage washable filters deliver reliable filtration comparable to pricier models like the FreAire, but at a more accessible price point. The real-time air quality monitoring and auto mode provide an intelligent cleaning experience, while sleep mode ensures quiet operation during rest. The inclusion of aromatherapy options adds a layer of customization, and operating two units allows for flexible placement in different rooms. The main limitation involves the need to replace filters every 3-6 months, and some users may wish for more detailed specs on CADR or filter lifespan. This product is best suited for budget-conscious buyers seeking comprehensive coverage with smart features in multiple rooms.
Pros:- Two units provide extensive coverage up to 1200 sq ft
- Washable filters reduce long-term costs
- Smart features like real-time air quality display and auto mode

GermGuardian HEPA Air Purifier – Large Room Air Purifier for Bedroom, Office, Dorm, and Home – Filters Pet Dander, Dust, Pollen, Smoke, Scents – AC4825E – 22″ Tower – Gray
The GermGuardian AC4825E stands out for its balanced combination of effective allergen removal and user-friendly features, making it a top choice for large rooms up to 743 sq. ft. This model excels in capturing 99.97% of airborne particles with its True HEPA filter, comparable to the KNKA APH4000, but it also includes an activated carbon pre-filter to tackle odors. Its optional UV-C light provides an extra layer of purification, which can be beneficial in homes with pets or smokers. Compared to the other options, it offers quiet operation and sleep mode, but the downside is that filter replacements can become costly over time. It’s less suited for very small spaces or those seeking the most advanced air quality monitoring. Overall, this pick makes the most sense for those needing reliable, multi-layer filtration without excessive complexity.
Pros:- Highly effective at capturing 99.97% of airborne allergens
- Suitable for large rooms up to 743 sq. ft.
- Includes optional UV-C light for additional purification
- Quiet sleep mode for undisturbed rest

- Suitable Rooms:Bedroom, Office, Dorm, Home
Our verdict“This is a well-rounded choice for those needing reliable large-room air purification with added odor control features.”
KNKA Air Purifier for Home and Bedroom Up to 1,695 Ft² in 1 Hour, APH4000, White
The KNKA APH4000 makes a compelling case for large, open-plan environments thanks to its AHAM-certified high-speed filtration and coverage of up to 1,695 sq. ft. In comparison with the GermGuardian, it offers faster air cleaning and a more versatile mode selection, including pet and eco modes, plus real-time air quality monitoring. However, its complexity can feel overwhelming, and frequent filter changes—every 3 to 6 months—add ongoing maintenance costs. Noise levels at higher speeds can also be noticeable, which might disturb sensitive sleepers. This model is ideal for those who prioritize rapid, large-area air cleaning and are comfortable managing multiple settings, but it’s less suitable for small or quiet-focused spaces.
Pros:- Effective high-speed purification for large rooms
- AHAM certified for verified performance
- Multiple modes including pet and eco for versatility
- Real-time air quality display for monitoring
Cons:- Frequent filter replacements every 3-6 months
- Setup can be complex with multiple filters and modes
- Higher noise levels at fast speeds
Best for: Large living rooms, open concept spaces, or users needing rapid air turnover in big areas.
Not ideal for: Individuals seeking a simple, plug-and-play device or those with limited budget for frequent filter replacements.
- Coverage Area:Up to 1,695 ft²
- CADR Smoke/Dust/PM2.5:226 CFM (384 m³/h)
- CADR Pollen:244 CFM (415 m³/h)
- Filtration System:Three-stage (pre-filter, HEPA, activated carbon)
- Noise Level:22-24 dB in Sleep Mode
- Filter Replacement Interval:Every 3-6 months
Our verdict“This is an excellent pick for large spaces requiring high-capacity air purification, provided you’re comfortable with regular maintenance.”
Air Purifier for Large Rooms up to 2600 ft² with Washable Filters, Turbo Mode, PM2.5 Display, Sleep Mode, Pet Hair Removal – White
This large-room purifier impresses with its ability to cover up to 2600 sq. ft., making it ideal for open floor plans or large living areas. The washable HEPA pre-filter reduces ongoing costs, unlike the replacement filters required by models like the GermGuardian or KNKA. Its real-time PM2.5 sensor and auto-adjustment of fan speeds help maintain cleaner air, and the quiet sleep mode ensures it won’t disturb rest. However, it lacks specific details on filter lifespan, and the initial cost could be higher, especially if replacement filters are needed at some point. Compared to smaller units, its size and energy use are considerations, but overall, it provides a practical, large-scale solution for those who want efficiency with ongoing savings.
Pros:- Covers up to 2600 sq. ft., suitable for large spaces
- Washable filters reduce ongoing costs
- Real-time PM2.5 monitoring
- Quiet operation in sleep mode
Cons:- Lack of detailed filter lifespan information
- Initial size and energy consumption may be high
- No advanced filtration stages beyond basic HEPA
Best for: Large households or commercial spaces seeking a cost-effective, low-maintenance air purifier.
Not ideal for: Small bedrooms or users who prefer devices with detailed air quality monitoring or advanced features.
- Coverage Area:Up to 2600 sq. ft.
- Air Intake:360°
- Noise Level:22 dB in Sleep Mode
- Fan Speeds:4 adjustable
- Timer:2/4/6/8 hours
- Certifications:ETL / FCC / EPA / CARB / DOE
Our verdict“A practical choice for large areas that benefits from washable filters and simple operation, though it requires attention to filter maintenance.”
ECOSELF Air Purifier for Large Rooms Up to 1800 Ft², HEPA Filter
The ECOSELF HEPA Air Purifier offers an effective solution for large rooms up to 1800 sq. ft., with its 360° air intake and automatic fan speed adjustment based on real-time PM2.5 readings. Its low noise level of 20 dB makes it suitable for bedrooms or quiet spaces, and the adjustable timer adds convenience. While its performance is comparable to the KNKA or GermGuardian in terms of coverage, the lack of specific filter replacement information or lifespan details could be a concern for long-term maintenance. This device excels at maintaining clean air with minimal user intervention, but users should consider potential higher costs for filters or sensors. It’s best suited for those prioritizing quiet operation and automatic adjustments over manual control complexity.
Pros:- Efficient 360° air intake for fast cleaning
- Auto-adjusts fan speed based on pollution levels
- Very quiet operation in Sleep Mode
- Real-time air quality display
Cons:- No clear info on filter replacement frequency
- Limited details on filter lifespan or cost
- Potentially higher device cost for large coverage
Best for: Bedroom users or those needing quiet, automatic air cleaning in large rooms.
Not ideal for: People who want detailed air quality data or frequent filter updates, as info is limited.
- Coverage Area:Up to 1800 sq ft
- Air Intake:360°
- Noise Level:20 dB in Sleep Mode
- Timer:1-24 hours
- Sensor:PM2.5 real-time monitoring
Our verdict“A strong choice for quiet, automatic large-room air purification, especially in bedrooms or quiet spaces.”
Air Purifiers for Bedroom, FULMINARE H13 True HEPA Filter
The FULMINARE H13 True HEPA Air Purifier is tailored for smaller spaces, such as bedrooms up to 215 sq. ft., with ultra-quiet operation at around 24dB, making it ideal for sleep environments. Its H13 filter provides high-efficiency particle removal, comparable to larger models but in a more compact form. The device’s multiple timer settings add convenience, but frequent filter replacements—every 3 months—can increase long-term costs. Compared to larger, more feature-rich units, it offers less coverage and fewer advanced modes, but it excels where minimal noise and simple operation are priorities. This pick makes the most sense for individuals seeking a dedicated bedroom purifier that operates without disturbance.
Pros:- Highly effective H13 HEPA filtration
- Very quiet operation around 24dB
- Compact and portable design
- Multiple timer settings for convenience
Cons:- Requires filter replacement every 3 months
- Limited to rooms up to 215 sq. ft.
- Fewer advanced features compared to larger units
Best for: Individuals needing a quiet, effective air purifier for small bedrooms or personal spaces.
Not ideal for: Large rooms or open spaces, where coverage is insufficient and more robust filtration is needed.
- Filter Type:H13 True HEPA
- Coverage Area:215 sq ft / 20 m²
- Noise Level:24 dB
- Timer Settings:2, 4, 8, 10, 12 hours

How We Picked
Products were evaluated based on performance, coverage area, ease of use, build quality, and value for money. We prioritized models with proven filtration efficacy, especially HEPA filters, and considered noise levels for quiet operation. Additional features like smart controls, filter maintenance, and design versatility influenced the rankings. Our goal was to identify options suitable for different room sizes, budgets, and user needs, ensuring each product offers clear advantages and tradeoffs for specific use cases.Factors to Consider When Choosing Air Purifiers
Choosing the right air purifier involves balancing several key factors to match your environment and needs. Beyond basic filtration, consider coverage area, noise levels, filter maintenance, and additional features. Making an informed decision means understanding how these elements impact performance, convenience, and long-term costs, helping you avoid common pitfalls like underestimating room size or overpaying for unnecessary features.Room Size and Coverage
Matching your air purifier’s coverage to your room size is critical. An undersized unit will struggle to keep air clean, while a very large model might be unnecessary and more expensive. Always check the manufacturer’s specifications for maximum square footage, and consider potential future needs if your space changes. Proper sizing ensures efficient filtration and quieter operation, as larger units are often designed for bigger spaces.
Filtration Technology and Effectiveness
HEPA filters are the gold standard for removing airborne particles like pollen, pet dander, and dust. Some models include additional layers, such as activated carbon, to target odors and chemical pollutants. The quality of filters directly impacts the purifier’s ability to improve air quality, so investing in a model with certified HEPA filtration typically offers better results. Be mindful of filter lifespan and replacement costs—cheaper filters may need more frequent changes, increasing long-term expenses.
Noise Levels and Operating Modes
Quiet operation is vital if you plan to use the purifier in bedrooms or workspaces. Many models feature sleep or quiet modes that reduce noise without sacrificing filtration. Pay attention to decibel ratings and user reviews about noise, especially for models placed in sensitive environments. A quieter unit may have fewer features or slower fan speeds, but it can make a significant difference in everyday comfort.
Smart Features and User Interface
Smart controls, such as app connectivity, air quality monitoring, and auto modes, add convenience but can increase the price. These features allow real-time tracking and remote adjustments, which are valuable for busy households. However, not everyone needs smart capabilities, and some users prefer simple, manual controls for ease of use. Consider whether these extras justify the extra cost based on your tech preferences and lifestyle.
Maintenance and Long-Term Costs
Filter replacement frequency and costs vary widely; washable filters can reduce ongoing expenses but may require more frequent cleaning to maintain effectiveness. Some models include indicator lights to alert you when filters need changing, simplifying upkeep. Budgeting for replacement filters is essential, especially if you plan to run the purifier continuously. Choose a model with readily available filters and clear maintenance instructions to avoid surprises later.
Energy Efficiency and Size
Energy consumption can add up if the purifier runs constantly, so look for models with Energy Star ratings or low power modes. Size and design also matter—compact units are easier to place in small spaces but may have lower capacity, while larger units can handle bigger rooms more effectively. Balance size, power, and energy use to optimize both performance and operating costs.
Frequently Asked Questions
How often should I replace the filters in my air purifier?
Most HEPA filters need replacement every 6 to 12 months, depending on usage and air quality. Some models include filter life indicators to help track when replacements are due, making maintenance more straightforward. Regular filter changes are essential for maintaining filtration efficiency and preventing mold or bacteria buildup inside the unit. Always follow the manufacturer’s recommendations for your specific model to ensure optimal performance.
Can I leave my air purifier running 24/7?
Yes, most modern air purifiers are designed for continuous operation, especially if they feature energy-efficient modes. Running your purifier constantly can help maintain consistently clean indoor air, particularly in environments with pets, smokers, or high pollen counts. However, consider energy costs and noise levels, and choose a model with adjustable fan speeds or sleep modes for quieter, more energy-efficient operation during nighttime.
Are smart features worth the extra cost?
Smart features can add significant convenience, allowing you to monitor air quality remotely, receive maintenance alerts, and customize settings via apps. If you value automation and real-time data, these features justify the extra investment. However, if you prefer simple controls or are on a tighter budget, basic models without smart capabilities can still provide excellent filtration without the added complexity or cost.
How do I know if an air purifier is effective against pet odors?
Effective removal of pet odors depends on the presence of activated carbon filters alongside HEPA filters. Look for models explicitly mentioning odor control or pet-specific features. Regular filter maintenance is crucial, as filters can become saturated with pet dander and odors over time, reducing effectiveness. Proper placement and running the purifier continuously can also help keep your indoor air fresh and odor-free.
Is a more expensive air purifier always better?
Not necessarily. While higher-priced models often include advanced features, larger coverage, and quieter operation, the best choice depends on your specific needs and room size. An expensive unit may be overkill for small spaces or casual use, where a more affordable model suffices. Conversely, for large rooms or allergy sufferers, investing in a premium model can provide noticeable improvements in air quality and comfort, justifying the higher cost.
Conclusion
For general use in small to medium homes, the Levoit Air Purifier for Home Pets Hair Allergens offers a quiet, effective solution at a reasonable price, making it ideal for allergy sufferers and pet owners. Those with larger spaces or specific needs, like odor control or smart features, should consider premium options like the FreAire HEPA Air Purifier. Budget-conscious buyers can find reliable performance in models like the VEWIOR 2 Pack, especially if multiple units are needed. Beginners seeking simplicity should prioritize models with straightforward controls, while allergy-sensitive users benefit from higher-end, multi-stage filtration. Ultimately, choosing the right purifier depends on your room size, air quality concerns, and desired features.
