The 5 Best Air Purifiers


Good air quality isa very important factor in maintaining good health, but it may surprise you that good air quality can be quite hard to come by naturally, especially if you have allergies or asthma, or if you live in a city or around smokers. The air can then be filled with lots of contaminants that can irritate your lungs. Investing in an air purifier can help eliminate this problem and ensure that you can have good air quality within your own home. Wise Think is here to help you find the best air purifier with our top five list.

What Is an Air Purifier?

An air purifier is an electronic air filtration device that actively removes contaminants such as pollen, dust, and mold spores from the surrounding air. Air purifiers are especially useful and important devices for people with allergies or asthma, as the purifiers reduce the amount of allergens in the air. Air purifiers circulate the air within a given area through its system, where it traps the contaminants via an internal filter and allow the machine to push out cleaner air. Air purifiers will repeat this process continuously over time to ensure the most optimal filtration.

The most effective and safest air purifiers will have two notable features: a high clean air delivery rate (CADR) rating and a high-efficiency particulate air (HEPA) filter. A CADR rating is especially useful for determining the rate at which an air purifier can filter the air of contaminants. The higher the number, the faster it can perform. HEPA filters are the most effective filters available since they meet the government standard for removing particles as small as 0.3 microns. It is also important to avoid ozone air purifiers as they have a high likelihood to cause lung problems.

Top 5 Air Purifiers

IQAir New Edition HealthPro Plus

The IQAir New Edition HealthPro Plus air purifier has been named Consumer Search's Best Overall Air Purifier, and it is definitely the best option to get if air quality is a major concern for you.

It comes with a HyperHEPA filter that allows it to trap particles as small as 0.003 microns, which is way smaller than what a normal HEPA filter can remove. There's also a V5 filter that allows the HealthPro Plus to be effective at chemical and odor removal as well. The HealthPro Plus is ideal for very large rooms, as it has a reported coverage of up to 1,125 square feet. Users have also said that it is also very easy to use thanks to its advanced yet intuitive control panel and that it delivers an overall quiet performance.

While it won't hurt your lungs, its high price tag can hurt your wallet quite a bit, especially when you add in the cost of replacing its filters. But you can breathe easily knowing that IQAir New Edition HealthPro Plus does give you an incredible package for the price.

Blueair 503

A Consumer Reports recommended pick, the Blueair 503 air purifier is another solid option that delivers quite a few neat features at a more reasonable price.

The BlueAir 503's most standout feature may be its patented HEPASilent technology, which uses a filter as well as an ionizer to more effectively eliminate contaminants while maintaining low noise performance and zero ozone emissions. It has a great CADR rating of 375 out of 400 for eliminating smoke, pollen, and dust, as well as an Energy Star qualification for its low power consumption.

The BlueAir 503's built-in SurroundAir system allows it to achieve the most optimal air purification by drawing in the dirty air through the bottom of the unit and then releasing the purified air through the top, resulting in cleaner air being circulated throughout the room. It can filter all air within an area of up to 580 square feet, and it also comes with a very useful filter replacement indicator.

The Blueair 503's main downside is that it can be very expensive to maintain. But if that doesn't bother you too much, then the Blueair 503 definitely won't disappoint you otherwise.

Whirlpool AP51030K Whispure

Another Consumer Search top pick, the Whirlpool AP51030K Whispure air purifier delivers the best balance of performance and cost on our list.

To start off, the Whispure uses a carbon pre-filter and true HEPA filters to clean all air within a 500 square feet radius, and its high CADR rating of 315 shows its effectiveness at eliminating dust, pollen, and cigarette smoke. These specifications are already pretty impressive for an air purifier of its size and price. Beyond its effective filtration capabilities, many users have also praised the Whispure for its quiet performance on both its highest and lowest speed settings as well as its simple-to-use electronic controls that include both turbo and sleep modes along with a filter status indicator that will indicate when a filter needs to be replaced

While the Whispure comes with an attractive price tag, replacement filters for this unit are really expensive and may add up over time. Regardless, the Whirlpool AP51030K Whispure overall leaves little to complain about.

Honeywell 50250

The Honeywell 50250 air purifier is an Amazon Best Seller that's also another Consumer Search recommended choice. While it's advertised as being ideal for extra large spaces, the 50250 is actually more ideal for smaller rooms since its filtration range is only up to 390 square feet, which is the smallest on our list.

Despite that, the 50250 still provides effective contaminant removal thanks to its HEPA filters and its patented 360-degree air intake system, which allows it to draw in air from all around the unit. There's also a carbon-activated pre-filter that helps eliminate odors as well. It also comes with an Intelli-Check Electronic Filter Indicator that will notify you of when filters need to be replaced, but overall, the 50250 lacks many of the nice electronic controls found in higher-priced options.

The 50250's biggest shortcoming seems to be its noise performance, as many users have reported that it makes noticeable noise on its lowest setting and that it can get pretty loud when used at its highest speed. In the end, if you're looking for a low-cost, straight-forward air purifier, then the Honeywell 50250 is well worth considering.

Holmes HAP756-U

If you're looking for an air purifier that provides the most value without breaking the bank, then the Holmes HAP756-U air purifier is the most ideal choice for you.

What makes the HAP756-U such a great value is that it contains a number of features and specifications that you'd expect to find a good high-end air purifier, including true HEPA filters, a filtration range of up to 418 square feet, a filter indicator, and even a multiple setting timer that'll allow it to run for up to 16 hours before automatically turning it off, all within a very portable design. On top of all that, the HAP756-U is also Energy Star qualified and includes a carbon pre-filter enhanced with Arm & Hammer baking soda to effectively eliminate odors as well.

However, users have reported that the HAP756-U works most effectively eliminating contaminants only at its highest speed, and that while it performs quietly at its lowest speed, it can be quite loud otherwise. Nitpicks aside, you will find that the Holmes HAP756-U air purifier is hard to beat for the price.
