’Tis the season to spend more time in our humble abodes, but before we snuggle in, it might be time to clear the air. According to the US Environmental Protection Agency, the average person absorbs an estimated 72 percent of chemicals in their own homes. Mold, household cleaners, pesticides, gases such as radon and carbon monoxide, and building materials such as asbestos, formaldehyde and lead can linger in the home. When breathed in, they can remain in our lungs and potentially cause heart attacks, strokes and skin aging. These pollutants release ultra fine particles as small as 0.1 microns into the air, which the lungs absorb quickly and easily. Unfortunately, they are very hard to trap in standard air purifiers. So we recently tried out Dyson’s Pure Cool air purifier and fan, which is said to clear 99.95 percent of even the most microscopic particles in the air. Here’s what we found.

The Pure Cool was designed in keeping with Dyson’s commitment to compact technology and design. The small DC motor is wrapped with a high-efficiency 360° Glass HEPA filter that draws in air from all angles. This technology is designed to keep potentially toxic ultra fine particles completely trapped within the filter. The 360º Glass HEPA filter absorbs up to 99.97 percent of particles as small as 0.3 microns, because it is so densely woven and packed together. The high-efficiency filter fiber consists of 11.8 square feet of borosilicate (non-synthetic) microfibers, pleated 254 times. Like a vacuum, a layer of rubber seals the filter and keeps even the finest of microns from escaping back into the room. Its special layer of odor-eliminating carbon granules is an added bonus and can be used to reduce cooking odors (in my case) or fumes from painting rooms in your home. Of course, this is all a little hard to measure, so how exactly do you test its purifying abilities? I set out on a mission.

THE PROS

Purifies and removes odors in small spaces

First, I tested the purifier in a small standard bedroom. We had cooked a pungent meal on a cold evening, so it was an opportune time to determine whether or not the Dyson could eliminate a noticeable amount of odor and oils in the air. I set the fan to mid-level airflow and oscillated it throughout the closed room. Within 15-20 minutes, I noticed a significant difference in air quality, and I was starting to breathe easier. I turned it down to the lowest setting and set the built-in sleep timer for 7 hours (the timer can be set for up to 9 hours). When I awoke, the odor was completely gone and I was breathing better than I’d ever breathed in my home before. The bedroom and the air felt lighter, and it was easier to breathe. There was still a lingering aroma in the rest of the house, so I deployed the Pure Cool in our living room. Although it did not clear the air in my entire 2-story home, it made a dramatic difference in the air quality of my living room and nearby areas.

Quiet

This “Quiet Mark-accredited” appliance is so silent, I hardly noticed it was on throughout the night. When you have the device powered to levels 1-3 (used purely for purification, not for blowing cool air), you can barely hear a thing. It’s very useful for night-time purification. When running the fan at a higher air pressure for cooling, you’ll definitely hear the airflow, but it isn’t very loud or obnoxious at all. It’s definitely one of the quietest purifier fans I’ve ever come across.

Comfortable air pressure

The Pure Cool’s Air Multiplier™ technology does circulate air rather seamlessly. Even when powered to the highest fan level, the air pressure is not forceful or bothersome like other fans.

Easy maintenance

The Pure Cool is also extremely easy to clean – it takes less than a minute to replace the filter, which only needs to be replaced after six months (or 4382 hours) of continuous use. (But I haven’t actually done this yet).

THE CONS

Price

Dyson’s Pure Cool isn’t the cheapest purifier or fan out there (it retails for around $499.99), but you’re really getting two very effective appliances in one. In the colder months, the Pure Cool can be used as a purifier using the lowest settings of 1-3. In spring and summer, just bump up the fan power to levels 4-10 and instantly cool and purify your space with a long-range of circulated airflow. When you consider all of that, the price isn’t outrageous, but it is certainly an investment. It’s also worth checking Amazon and the Dyson website for discounts and specials.

All in all, I’ve been quite pleased with the Pure Cool. If you have breathing sensitivities or health issues and are really looking to invest in an effective combination air purifier/fan, I would recommend it.
