Clean air is no luxury. For people with asthma, allergies, sensitivity to odors, and just about anyone who wakes up in the morning feeling stuffy, the invisible particulates and vapors floating in the air are more than minor irritants. An air purifier can make a world of difference by filtering the air and trapping the pollutants, sending fresh, clean air back into the room and enabling inhabitants to breathe a whole lot easier. scoured online assessments by experts and consumers to find the best cheap air purifiers -- top-performing models under $250 for large rooms and $100 for small rooms. As bonus picks, we've got an air cleaner for pet owners, a model with "smart" capabilities, and a big-ticket purchase from popular brand Rabbit Air for those willing to splurge on greater cleaning capacity and loads of convenience features.

Prices and availability may vary.

Good Air Purifier With Permanent Filter
Est. Price: $46 | Buy it on Amazon

- Permanent HEPA-grade filter can be cleaned with a vacuum; no need to buy replacements.
- Tabletop size; can be positioned vertically or horizontally.
- Good for trapping allergens.
- 3 fan speeds to adjust for lower noise or faster performance.
- Runs very quietly, according to many reviews.

- Only 1 level of filtration; no carbon filter to catch irritants from chemicals or grease.
- Some users wish it had a "true" HEPA filter capable of trapping 99.97 percent of airborne irritants as small as 0.3 microns, instead of 99 percent of particles as small as 3 microns.
- Scattered complaints about ineffective performance.
- Short 1-year warranty.

Takeaway: A hefty majority of reviewers cheer the Hamilton Beach True Air 04386 for keeping the air breathable in homes with pets and residents with limited tolerance for pollen, mold spores, and dust mites. Some consider this the best air cleaner they've ever used, and many report that it rids the air of particulates almost noiselessly when set on low. Compact enough to move around the house or take on vacation, it can clear rooms up to 160 square feet. Most reviewers appreciate the easy-clean, money-saving design, with the permanent HEPA-grade filter, although a few feel cheated that it falls a tad short of the "true" HEPA standard.

Good Air Purifier for a Small Room
Est. Price: $40 | Buy it on Amazon

- Very compact, desktop footprint; can be set flat or upright.
- Multi-level filtration: proprietary filter with extra odor-absorbing capacity (carbon, baking soda, and zeolite) as well as a HEPA-type filter.
- Users can upgrade to a variety of specialized Aer1 filters for more concentrated or customized cleaning.
- 3 fan speeds.
- 3-year warranty.

- Some users object to the ionizer feature, despite the option to turn it off.
- Scattered claims about ineffective performance, assorted malfunctions, chemical odors, and unacceptably loud noise.

Takeaway: Holmes air purifiers have long earned praise for their excellent value, quickly clearing air of litter box and food odors, hairstyling and garage fumes, particles drifting out of air ducts, pollen, smoke, and more. The desktop Holmes HAP242-NUC-1 is no exception. It's intended for small rooms up to 109 square feet, and scores of users tell of placing it in bathrooms, bedrooms, and kitchens to great effect. It's also said to be a good air purifier for the office. The HEPA-type filter traps fewer pollutants than a "true" HEPA filter (99 percent of particles as small as 2 microns vs. 99.97 percent of particles as small as 0.3 microns), but users don't seem to notice the difference. Those wishing for greater cleaning power can easily switch to a higher-grade filter, which also needs replacing less frequently.

Good Air Purifier for Large Rooms
Est. Price: $240 | Buy it on Amazon

- Makes a noticeable difference in air quality almost immediately, reviewers say.
- Air is refreshed 4.8 times an hour in rooms up to a very spacious 490 square feet.
- HEPA filter and active carbon pre-filter for multi-level cleaning.
- Indicator light to signal when the filters need replacing.
- Electronic controls, including a timer and 8-hour sleep mode.
- 4 fan speeds; "turbo" setting.
- Engineered to run quietly; Whispure models are known for hitting less than 50 dB on max speed.
- Energy Star certified.
- 5-year warranty on the motor and 30-day money-back guarantee that it will prove quieter than comparable models.

- Only a handful of consumer reviews for this particular model; we relied on reviews of a previous version in making this pick.
- Some disappointment with the build quality of that predecessor, and the 1-year standard warranty is short.

Takeaway: A previous model, the Whirlpool AP51030K, earned plaudits from users and experts alike for its features and performance. It scored points with testing sites for removing common irritants like dust, pollen, and smoke at both high and low speeds, as well as quiet operation. The new Whispure WP500P is said to be quieter still and is Energy Star certified. Based on the few available user reviews, we expect that it will at least meet the standards set by the older model, including removal of 99.97 percent of particulates as small as 0.3 microns, thanks to the HEPA filter.

Reviews point to a reduction in allergy and asthma symptoms when used in a bedroom, less dust in a closet that was full of it, and protection against germs floating around an office. Some find the fan a noisy distraction, but others shrug it off as background music -- a fitting description for a unit looks more like a stylish little speaker than an air cleaner.

Bonus: Air Purifier With Smart Connectivity
Est. Price: $181 | Buy it on Amazon

- User-friendly and effective against odors, reviewers write, with a noticeable difference in the amount of dust and the breathability of the air.
- Can be operated remotely with a smartphone or tablet via Bluetooth.
- Auto settings on the app can trigger operation based on specified levels of allergens in the outside air.
- Multi-level filtration: activated carbon pre-filter and true HEPA filter.
- Sensor for auto-on to clear out volatile organic compounds (VOCs).
- 4 fan speeds/"purification levels."
- Air is cleaned up to 5 times an hour in spaces up to 310 square feet.
- Customizable on/off schedule; programmable timer for 1 to 18 hours.
- Indicator lights for each filter; dimmer for all LED lights.
- Energy Star certified.
- 5-year warranty.

- Some users aren't thrilled with the app, citing a limited proximity range, problems syncing, and functions not working.
- Some grumbling in reviews about excessive noise at higher speeds and a few doubts concerning overall effectiveness.

Takeaway: The big lure of the Honeywell HPA250 is its smart capabilities. Many users like the convenience of the auto features and the ability to create an on/off schedule, all for a relatively modest price. Some contend that the app isn't quite ready for prime time, however. As far as air purification goes, the consensus opinion is that this model does a fine job, and its large coverage area is appreciated. For those skeptical of the smart technology, Honeywell offers non-Bluetooth models with almost identical specs for rooms of different sizes (HPA100, HPA200, and HPA300) that are highly regarded by testing sites.

Although this model is engineered for small to midsize rooms up to 193 square feet, some users tell of good results in larger spaces.
