The Honeywell QuietClean HFD-110 is adequate for small, dusty rooms and is a nice purifier for people with very limited budgets. But the device suffers from misleading marketing gimmicks, and the performance leaves a lot to be desired. Bottom line: there are better options out there for less money.
The Mammoth Classic is a nice entry-level, low-power air purifier. Best for use in small and medium rooms, the Classic provides fine value at its price point – but it still isn’t all that powerful. People with serious allergies might look elsewhere.
The Winix WAC9500 is a well-designed unit that boasts strong performance, energy efficiency and several nifty built-in monitoring features. The device is a great match for people struggling with allergies, but doesn’t perform as well when it comes to entrenched odors.
The Honeywell AirGenius5 HFD320 is a versatile, well-performing purifier ideal for medium-sized rooms. It's extremely energy efficient, particularly effective against allergens, and doesn't have any serious drawbacks. But while this device is a jack of all trades, it seems to be a master of none.
The Honeywell HFD-120-Q is a great air purifier for small and medium-sized rooms; it delivers strong performance for the price, you won't spend a penny on long-term maintenance/filter replacement and it boasts strong energy efficiency. But if you're looking for an air purifier to handle large rooms, there are better options for the price.
The Alen BreatheSmart FIT50 is as powerful as they come, and energy efficient to boot. The device is intelligent, well designed and packed with nifty features. But the price tag might be too much for many shoppers.
The Honeywell QuietAir 17000-S is fine for small or medium-sized bedrooms, and performs well in these spaces. But it isn't especially powerful, energy efficient or quiet. In all, this is a solid machine with major limitations.
The O-Ion B-1000 is inexpensive, low-maintenance, and is adequate for small bedrooms. But the machine isn’t very powerful, its coverage area is limited and it isn’t equipped to deal with small particulates. It also generates very small levels of ozone, so it's not a good match for people with respiratory issues.
The Honeywell HPA 300 is a no-frills, heavy-duty device that can churn through large spaces with ease, works quickly, and is relatively energy efficient. But this unit is bulky and probably impractical if you’re just looking to use in a small bedroom.
The Coway AP-1512HH is effective, quiet and extremely intelligent. It handles odors and particulates with ease, and the device is Energy Star certified. The biggest knocks on the unit are the way it manages dust, and the fact that it slows down when facing rooms over 400 square feet.
The GermGuardian AC4825 is inexpensive, exceptionally quiet and very well-made. But it works slowly and its not very powerful, which holds the device back from achieving outstanding value. All in all, an excellent entry-level air purifier for small rooms.
The Hamilton Beach TrueAir Compact Pet Air Purifier is inexpensive but very limited. The device is adequate for the reduction of light allergens and mild pet-related smells, and is designed for small bedrooms only. The True Air falters when it comes to more serious purification duties; this device isn’t built to handle strong odors or allergens, and is ineffective in medium or large rooms.
The P300 is a great budget-buy air purifier for people with mild air quality issues, and a great fit for bedrooms of all sizes. But it has its limitations, and isn’t ideal for people with severe allergies.
The Rabbit Air MinusA2 SPA-700A is one of the very best air purifiers on the market. It’s incredibly quiet, powerful and astonishingly intelligent; it’s well designed, energy efficient and extremely versatile to boot. The only drawback for some buyers will be the price point.
The Whirlpool Whispure AP51030K is a great match for people looking to eliminate allergens and other small particulates in small and medium-sized rooms. This device also offers great value for the price and is one of the best-selling units on the market. But the AP51030K is much less effective against odors; if you’re looking for a purifier to deal with smoke or chemical smells, look elsewhere.
The Winix 5300 is arguably the best value-buy on the market; the device offers unmatched performance for the price, can handle medium-large rooms, and is energy efficient and quiet. Plus, the unit will likely last for years. The 5300’s relative weakness is that it can struggle against heavy odors.
