Best Air Purifiers for Pets and Allergy Relief

TL;DR: The Levoit Core 300 White delivers 99.97% particle removal, covers up to 1095 sq ft, and packs a compact 220.98 mm depth, all for $84.94.

The Core 300’s standout spec is its 1095 sq ft coverage at a single air change per hour, backed by a 167 CFM pollen CADR and a 45 W Energy Star‑rated motor. At 7.9 lbs and dimensions of 220.98 mm × 220.98 mm × 360.68 mm, it fits neatly on a nightstand while still handling a typical bedroom‑sized space.

Compared with the other seven models, the Core 300 sits in the middle of the weight range—it’s heavier than the Core Mini (2.2 lbs) and Vewior (2.36 lbs) but lighter than the Vital 200S (13.2 lbs) and Shark HP301 (12.27 lbs). Its 1095 sq ft coverage outstrips the Core Mini’s 255 sq ft recommendation, yet it doesn’t reach the 1875 sq ft room size claimed by the Vital 200S.

Users consistently praise its compact footprint and the way it quickly eases pet‑related allergens, noting the “quiet” operation thanks to QuietKEAP™ technology. Professional reviewers highlight the VortexAir™ circulation that spreads clean air evenly across a room. The main complaints revolve around the lack of app connectivity and scheduling, which some shoppers miss for remote control.

Under the hood, the three‑stage system—washable pre‑filter, HEPA‑grade main filter, and ARC Formula™ activated carbon—captures 99.97% of particles between 0.1 µm and 0.3 µm, while the carbon layer neutralizes odors rather than just masking them. The one‑touch interface keeps operation simple, and the built‑in sleep mode lets you run it overnight without disturbance.

Best for: Most users looking for a well‑reviewed, reliable mainstream option — the Levoit Core 300 White offers Depth: 220.98 mm

Avoid if: You need coverage for large open‑concept rooms exceeding 1095 sq ft or want smart‑app control for automated scheduling.

TL;DR: The Levoit Core Mini White delivers True HEPA‑plus‑carbon filtration for rooms up to 255 sq ft, packs smart app control into a 2.2‑lb, ultra‑quiet package for under $50.

The standout spec is its 46 CFM clean‑air delivery rate paired with a three‑stage True HEPA + Activated Carbon filter that captures 99.97 % of particles. At just 2.2 pounds (998 g) and with dimensions of 190 mm × 190 mm × 160 mm, it fits comfortably on a nightstand or desk. Smart‑app integration and an auto‑dimming display let you monitor air quality from your phone, while a one‑touch button and sleep mode keep operation simple and whisper‑quiet at 24 dB.

Compared with the other seven units, the Core Mini is lighter than the Vewior Air Purifier (2.36 lb) and far lighter than the Afloia Kilo (4.4 lb) or the Levoit Core 300 (7.9 lb). Its footprint is also smaller than the Afloia Kilo’s 193 mm depth and height. While its 46 CFM CADR trails the Afloia Kilo’s 82 CFM and the Core 300’s higher ratings, the Core Mini still meets the AHAM‑verified coverage of 255 sq ft at one air change per hour. Noise on the low setting (24 dB) rivals the Vewior’s low‑mode ~18 dB, though the peak 57.7 dB at maximum speed is louder than many competitors’ advertised limits.

Users repeatedly praise the unit’s ultra‑quiet sleep mode, intuitive one‑touch operation, and noticeable drop in dust, pet dander, and odors. The built‑in air‑quality sensor and filter‑replacement indicator add convenience, and the included fragrance sponge lets you add a light scent. Professional reviewers highlight the AHAM verification and the whisper‑quiet low‑speed performance as strong points, but they also note that the maximum fan speed can exceed 50 dB, which may disturb light sleepers. Additionally, the effective coverage shrinks to under 180 sq ft when the fan runs at higher speeds, so the device is best suited for small bedrooms or dorm rooms.

Best for: Budget‑conscious buyers seeking a reliable entry‑level option — the Levoit Core Mini White offers CADR: 46 CFM

Avoid if: You need coverage for large open‑concept areas or a unit with higher airflow for rapid circulation

TL;DR: The Levoit Vital 200S White delivers medical‑grade HEPA filtration, a 1875 sq ft coverage area, and app‑controlled smart features, though its $169.99 price is higher than many mid‑range rivals.

The Vital 200S packs a 289 CFM pollen CADR, 254 CFM dust CADR and 250 CFM smoke CADR, giving it the firepower to clean large spaces quickly. Its three‑stage system—washable pre‑filter, HEPA‑grade main filter and activated carbon—captures 99.97% of particles down to 0.3 µm, while the infrared air‑quality sensor monitors conditions in real time. At just 24 dB on the lowest setting, it stays whisper‑quiet even during night‑time operation.

Compared with the other seven models, the Vital 200S is heavier than the Levoit Core 300 (7.9 lb) but lighter than the Blueair Pure 211i Max (22.7 lb). Its 15.6 in depth and 19.8 in height make it taller than the Core Mini, yet its 8.5 in width keeps it from dominating a corner. While the Core Mini and Vewior units sit under 3 lb, the Vital’s 13.2 lb build feels solid without being cumbersome, and it offers more fan speeds (7) than the Fellowes AeraMax (4) or Core Mini (3).

Customers rave about how well the purifier handles pet hair and dander, often noting the washable pre‑filter as a time‑saver. Reviewers also praise the 24 dB nighttime mode for undisturbed sleep. Professional reviewers highlight the impressive CADR‑to‑noise ratio and the AHAM verification as signs of reliable performance. The most common complaints revolve around the cost of replacing the combination filter and occasional hiccups with the VeSync app’s connectivity.

Beyond raw numbers, the Vital 200S includes a U‑shaped air inlet that channels larger debris toward the pre‑filter, a light sensor that adjusts fan speed automatically, and full smart integration via the VeSync app, Alexa and Google Assistant. With timer settings, a dedicated sleep mode, and a remote control, you can fine‑tune operation without leaving the couch.

Best for: Home and office users seeking a balance of features and value — the Levoit Vital 200S White offers Coverage Area: 1875 sq ft

Avoid if: You're shopping on a tight budget — it's priced at $169.99

TL;DR: With a medical‑grade H13 True HEPA filter that catches 99.99% of 0.03‑µm particles, the Afloia Kilo quietly covers up to 1,076 sq ft and offers smart‑free timer and sleep‑mode features.

The standout specification is its 99.99% filtration efficiency at 0.03 µm, backed by a 3‑stage system (pre‑filter, H13 True HEPA, activated carbon). It moves air at 140 m³/h (82 CFM), delivers a whisper‑quiet 22 dB operation, and can handle rooms as large as 1,076 sq ft—all while weighing just 4.4 lb and fitting into a 193 mm × 386 mm × 193 mm footprint.

Compared with the other seven models, the Kilo is heavier than the Levoit Core Mini (2.2 lb) but considerably lighter than the Levoit Core 300 (7.9 lb) and the Blueair Pure 211i Max (22.7 lb). Its CADR of 82 CFM outpaces the Core Mini’s 46 CFM, yet it falls short of the Core 300’s dust CADR of 153 CFM and the Vital 200S’s dust CADR of 254 CFM. Noise‑wise, the Kilo’s 22 dB is quieter than the Core Mini’s minimum 24 dB and far below the Shark HP301’s maximum 53 dB.

Customers repeatedly praise the ultra‑quiet sleep mode and the noticeable relief from pet dander, pollen, and smoke. Reviewers also like the seven‑color auto‑dimming lights for a personalized ambiance. On the downside, users note that the carbon filter struggles with strong odors and that the advertised 1,076 sq ft coverage feels optimistic for rooms larger than about 300 sq ft. Professional reviewers point out that the unit achieves roughly a 90% air‑quality improvement within the one‑hour purification window.

Best for: Budget-conscious buyers seeking a reliable entry-level option — the Afloia Kilo offers CADR: 140 m³/h (82 CFM)

Avoid if: You want the best value-per-dollar in its price range

TL;DR: The Vewior Air Purifier offers H13 True HEPA filtration that captures 99.97% of 0.1‑µm particles, covers up to 1200 sq ft, and runs quietly at ~18 dB, all for $34.99.

What really stands out is the three‑stage filtration system anchored by an H13 True HEPA filter that removes 99.97% of particles as small as 0.1‑0.3 µm. At 2.36 pounds and a compact 280 mm height, it fits easily on a nightstand or desk. The unit can exchange room air five times per hour and is rated for rooms up to 1200 sq ft, making it a solid choice for medium‑size bedrooms or home offices.

Compared with the other seven models in this roundup, Vewior sits in the lightweight camp: it’s a bit heavier than the Levoit Core Mini’s 2.2‑pound frame but considerably lighter than the Afloia Kilo (4.4 lb), the Blueair Pure 211i Max (22.7 lb), and the Fellowes AeraMax (13.8 lb). Its four fan speeds—including an auto mode—match the Fellowes AeraMax’s four‑speed offering, yet it provides fewer speed options than some premium units that list more granular controls. Noise-wise, Vewior’s ~18 dB low setting is quieter than the Core Mini’s minimum 24 dB, Afloia’s 22 dB, and the Shark HP301’s peak 53 dB, positioning it as one of the quietest choices for sleep‑time operation.

Users consistently praise the whisper‑quiet sleep mode and the convenience of the LED touch panel, noting that the device blends into bedroom décor without humming. Professional reviewers also highlight the reliable auto mode, which reacts to the built‑in PM2.5 sensor and displays real‑time air‑quality readings. However, many buyers point out that the advertised 1730 sq ft coverage feels optimistic; real‑world experience tends to align more with the 1200 sq ft claim. The limited fan‑speed range and lack of app‑based control are also mentioned as trade‑offs for the budget price.

Additional technical details include a 6‑step timer (2 h to 12 h), child lock, auto shut‑off, and a built‑in fragrance sponge for optional aromatherapy. The pre‑filter cover is washable, extending the life of the H13 HEPA core, which the manufacturer suggests replacing every 4.5 months.

Best for: Budget‑conscious buyers seeking a reliable entry‑level option — the Vewior Air Purifier offers Height: 280 mm

Avoid if: You need advanced features or professional‑grade performance

TL;DR: The Shark HP301 packs a 5‑year HEPA filter, 240 CFM CADR and 1,300 sq ft coverage into a 12.27‑lb unit, but its premium price and lack of app control may deter budget‑focused shoppers.

The headline spec is its 5‑year “NeverChange” True HEPA filter that captures 99.98 % of particles as small as 0.1 µm, meaning you won’t need to buy replacements for half a decade. Coupled with a CADR of 240 CFM, the unit can clean a room up to 1,300 sq ft, making it suitable for large living areas or open‑plan homes.

Compared with the seven other models in this roundup, the Shark sits in the middle of the weight spectrum at 12.27 lb—lighter than the Blueair Pure 211i Max (22.7 lb) but heavier than the Levoit Core Mini (2.2 lb). Its CADR of 240 CFM bridges the gap between the modest 153 CFM of the Levoit Core 300 and the higher 452 CFM dust rating of the Blueair Pure 211i Max. Coverage-wise, it falls short of the Levoit Vital’s 1,875 sq ft claim, yet it still exceeds the 1,095 sq ft coverage listed for the Levoit Core 300 at one air change per hour.

Everyday owners rave about the filter’s longevity, noting the “never‑change” system saves time and money. Reviewers also highlight the real‑time CleanSense IQ sensor that auto‑adjusts fan speed, the three‑level display brightness, and the programmable timer as convenient touches. Professional reviewers, however, caution that the unit isn’t certified for medical‑grade environments and that the odor‑neutralizer cartridge will need periodic replacement.

Technical extras include five fan speeds (Low, Medium, High, Max, Auto), an air‑info display showing clean‑air percentage and particle tracking, and a washable pre‑filter that can be vacuumed or rinsed. The unit runs on 54 W of power, draws a 1,829 mm cord, and comes with a two‑year warranty.

Best for: Buyers willing to invest in a proven, high‑quality option — the Shark HP301 offers Depth: 335.3 mm

Avoid if: You're on a tight budget, need medical‑grade air purification, or rely on app‑based control.

TL;DR: Despite a premium price, the Blueair Pure 211i Max delivers medical‑grade 0.1 µm particle capture, smart app control and coverage of up to 674 sq ft, making it a top pick for health‑focused households.

The standout figure is its Clean Air Delivery Rate of 452 cfm for dust, paired with a recommended room size of 674 sq ft and an Air Changes per Hour rating of 4.8. HEPASilent™ technology guarantees 99.97 % filtration efficiency down to 0.1 microns, while the integrated PM1, PM2.5 and PM10 sensors automatically adjust fan speed. At 22.7 lb the unit packs serious performance without sacrificing the Energy Star‑certified 46‑watt power draw.

Compared with the other seven models, the Blueair is heavier than the Levoit Core 300 (7.9 lb) and the Levoit Vital 200S (13.2 lb), but it also outperforms them on airflow. Its dust CADR of 452 cfm dwarfs the Levoit Vital’s 254 cfm and the Core 300’s 153 cfm, and it offers six fan speeds versus the Fellowes AeraMax’s four. While the Levoit Vital lists a larger coverage area, the Blueair’s 674 sq ft rating still exceeds the room‑size targets of most competitors, delivering faster cleaning for sizable living spaces.

Users consistently applaud the rapid reduction of allergens, smoke and pet dander, noting the seamless app integration for real‑time AQI monitoring and scheduling. Professional reviewers highlight the 360‑degree intake that distributes airflow evenly and the quiet night mode that runs at just 23 dB. The single‑filter design, however, means a full‑unit replacement every 7.5 months, and the 22.7‑lb chassis can feel bulky in tight apartments.

Best for: Buyers willing to invest in a proven, high‑quality option — the Blueair Pure 211i Max offers Air Changes per Hour: 4.8

TL;DR: The Fellowes AeraMax 290 delivers hospital‑grade 4‑stage filtration, 99.97% particle removal and covers up to 600 sq ft, but its premium $263.42 price and frequent filter swaps keep it in the high‑end niche.

What sets the AeraMax 290 apart is its four‑stage hospital‑type filtration that includes a True HEPA filter rated at 99.97% removal of particles ≥ 0.3 µm, an activated carbon layer for odors, and PlasmaTrue ionization. The unit also packs a 4‑speed fan (Low, Medium, High, Turbo) and runs on just 6 W in low mode, which helps keep electricity bills down while still delivering up to 600 sq ft of coverage.

Compared with the seven other models in this roundup, the AeraMax 290 is heavier than the Shark HP301 (12.27 lb) and the Levoit Vital 200S (13.2 lb) but lighter than the Blueair Pure 211i Max (about 22.7 lb). Its height of 638 mm makes it taller than most, and its depth of 207 mm is deeper than the compact Levoit Core Mini. Unlike the Levoit Vital, it does not offer smart‑app control, and it lacks a remote control that some competitors provide.

Reviewers consistently praise its ability to capture allergens, mold spores and smoke, noting that the AeraSmart sensor automatically ramps the fan speed when pollutants rise. Professional observers highlight the antimicrobial‑treated HEPA media and the ultra‑quiet operation. On the downside, the carbon filter needs replacement every three months and the HEPA filter annually, which adds to ongoing costs, and the premium price may deter budget‑conscious shoppers.

Best for: Those prioritizing quality and willing to pay for premium performance — the Fellowes AeraMax 290 offers coverage up to 600 sq ft and a 4‑stage filtration system.

Avoid if: You're shopping on a tight budget, need smart‑home integration, or prefer washable filters to minimize maintenance.
