What experts liked
High marks for quiet operation and ability to clean rooms up to 490 sq. ft. We love that it has four fan speeds and additional sleep and turbo modes for a variety of air-cleaning needs.
- BestReviews
The Whirlpool Whispure AP45030K is very efficient and can filter air up to 4.8 times per hour in a 490-square feet room. This efficiency is proven by the Energy-star certification, which is only awarded to products that meet specific requirements.
- ratingle
The Whirlpool Whispure is the best air purifier at removing airborne pollutants from your home, as indicated by its excellent CADR scores.
- Top Ten Reviews
This Whirlpool was the quietest portable model we tested, especially when run at its highest speed, where it aced our smoke- and dust-removal tests.
- Consumer Reports
What experts didn't like
The design is not as streamlined as some other models, and the filters are more costly than those of similar air purifiers.
- BestReviews
The main drawback to the Whispure is that it’s kind of big. This makes it awkward for smaller rooms. However, because it’s quiet and can be pushed right up against the wall and behind furniture, it doesn’t dominate a room too much and can be hidden away.
- ratingle
The air purifier lacks an auto mode that adjusts settings based on the ambient air quality in your home.
- Top Ten Reviews
Annual operating costs for this large-room model are on the high side, but allergy sufferers might appreciate its performance nonetheless.

An Overview On Air Purifiers

The reasons for buying an air purifier can be as numerous as the number of pollutants in the air — and indoors, that number tends to be bigger than most people would expect. Despite the best efforts of the filters in our air conditioners, pollen and dust particles can settle into carpets and upholstery. Mold spores can grow in moist areas. And if there are pets or smoke involved, expect dander and carcinogens to be part of every breath.

Whether you suffer from allergies or just want to eliminate the smell associated with all this particulate matter, a good air purifier can be an essential accessory in any room. But how are they different from the filters we already have in our regular AC?

All that depends on the purifier. Most models circulate air through a HEPA (High-Efficiency Particulate Air) filter, and often more than one. HEPA filters are certified to trap particulate matter as small as 0.3 microns, which covers dust, pollen and most bacteria. Purifiers like the IQAir HealthPro Plus boast a medical-grade Hyper-HEPA filter that will go down to 0.003 microns — enough to pick smoke out of the air.

In conjunction with this, the more high-tech air purifiers can employ an extra line of defense. The Germ Guardian uses an optional UV light that renders many micro-organisms sterile, and an activated charcoal filter that can actually pull in and neutralize toxins through electrostatic attraction. There are also models like the Coway Mighty Air Purifier that can ionize incoming particles, which are then sucked in by metal plates or other treated substances.

A word of caution on ozone, though. While they’re less common these days, some air purifiers generate ozone, which, according to the manufacturers, can deodorize and disinfect the air. The jury is still out on those claims, and in fact the presence of ozone in confined spaces can be more harmful than the pollutants you’re trying to get rid of.

For a measure of general effectiveness, you can look for a rating on most air purifiers called the CADR — Clean Air Delivery Rate. It’s a number that represents the cubic feet per minute (CFM) of air that has been cleared of all the particles of a given size. These ratings are recognized by the EPA and can be found on most devices. If you can’t find them, the number is fairly easy to calculate: Just take the CFM on the air purifier and multiply it by the percentage of a certain particle (smoke, pollen, etc.) that the machine can remove.

DYWM Fun Fact

That air purifier humming away in the corner of your room may look tranquil, but it was initially created for military use. The HEPA filters that are so common today were first employed to keep lab workers safe at the Manhattan Project, the 1940’s scientific effort that led to the creation of the atomic bomb. Back then, scientists were less concerned with their ability to keep their allergies in check. They were using the filters to block out as much radioactive material as possible.

The Air Purifier Buying Guide

  • One of the first things you’ll want to consider when buying an air purifier is the kind of room you’ll be using it in. When it comes to price, this is usually the primary factor. A workhorse unit that can handle an entire living room and kitchen (the IQ Air HealthPro Plus, for example) is going to run you significantly more than a machine that’s meant for a home office (the Coway Mighty) — for good reason.
  • Are you looking for protection from allergies or just need to freshen up the air? A quick look at the specs for the purifier should tell you what particles it can effectively remove from the air. Again, a HEPA filter is going to do the trick for most common irritants and odors, including pet hair and dust. But if you live in a smoker’s house, look into something more robust.
  • Much like your air conditioner, you’ll likely be keeping an air purifier on for as long as you plan on breathing the air in that room. In a lot of cases, that might be all day, so power consumption matters. Frugal users might want to check out the wattage specs on prospective models. There are also features that can mitigate that electricity drain, such as timers. In most cases, your air purifier won’t be running all the time. It’ll cycle the air through a few times an hour, and you can adjust that number more or less with most models. The Alen BreatheSmart does one better, with a handy sensor that measures the air quality in the room and automatically adjusts the fan speed and cycle time to match its needs.
  • Another thing to figure into your price point are the filters. Like your AC, there’s upkeep involved. Check not only the price of your filter, but the frequency with which you’ll need to replace it.
  • Since they’re meant for indoor use, most air purifiers are better looking than, say, that wall AC unit you had in your dorm room at college. That said, few people want them as the focal point in a room. If you’re getting one for a small room, you likely want a small purifier — or at least one that’s nondescript. Sleekly designed at less than 17″ x 19″, the Coway Mighty fits the bill on both counts.
