Which is the Best Air Purifier for Asthma?

by Matthew Cook SEO Copywriter

I think the Winix 5500–2 is the best air purifier for asthma. Well, it’s not the only effective air purifier for the condition. Indeed, there are many other great options on the market. Here are 12 good reasons I’d choose the Winix 5500–2 again and again.

1. The air purifier uses true HEPA filters.

Medical researchers, allergists, and asthma experts recommend air purifiers with True HEPA filters to asthma and allergy sufferers. That’s because they’re super effective. Did you know that the U.S. army corps of engineers led the development of the first ever True HEPA filter way back in the 1940s to capture radioactive dust? I thought you should know.

2. The air purifier removes 99.97% of a wide range of indoor air contaminants. That aligns with the EPA’s air purification standard for portable room air cleaners. They should filter out at least 99.97% of particles larger than 0.3 microns. Just in case you have no idea how big a micron is, it equates to about 0.00004 inches.

3. It uses Winix’s famous PlasmaWave technology. The technology enables the air purifier to break down and eliminate chemical vapors and odors without adding harmful levels of ozone back into your indoor air.

4. It uses a washable AOC filter. Now, filters aren’t cheap, and anyone who buys them does so because they need to. It’s no fun. An air purifier that uses a washable filter will save you tons of money over the long term. And that’s a BIG reason to choose the Winix 5500–2. By the way AOC means Advanced Order Control.

5. It’s smart. It’s a modern machine that’s easy to operate and comes with lots of great features that deliver convenience. For example, it comes with a sensor that scans the air and reports its current quality level to the fan. If the air needs a bit of scrubbing, the fan kicks into gear and kicks out all those freaking allergy triggers, particulates, and odors.

6. Features a smart Sleep mode that works great. When nighttime comes, the device’s digital sensor adjusts fan speed and dims the indicator lights so you can sleep like a log.

7. It’s neither too big nor too small. It’s just the perfect size for a medium-sized room or a relatively larger one. It’s designed for rooms measuring about 19″ x 19;” in other words, it’s built to purify up to 360 sq. ft. Just about the right size for your bedroom, kitchen, kid’s bedroom, or living room.

8. It’s affordable. Believe me, you’d be hard-pressed to find an air purifier that costs slightly over $150 on Amazon (as of this writing) that delivers the kind of results this Winix does. With this option, you’re getting loads of value for your money.

9. It comes with an LED filter-change indicator light. The light warns you when the filter is about to expire and needs to be replaced. No need to remember dates.

10. It’s portable. It weighs just over 15 lbs. If you’re a renter and likely to move in the future, loading the device into the truck would be quite easy.

11. 87% of people who have used the Winix 5500–2 have rated the product 4 or 5 stars on Amazon (as of this writing).

12. It’s AHAM, CARB-certified, and Energy Star rated. That tells you it’s been tested by independent labs and found to perform up to a certain level. By the way, AHAM is a private organization that tests air purifiers and assigns them various performance-related numbers including CADR (clean air delivery rate).

The Winix 5200–2 consumes a relatively small amount of energy, about 70 Watts. I’ve not seen many air purifiers that require such a small amount of power to operate. That means you won’t see any significant change in your electric bill. Just in case I’ve lost you, CARB is an abbreviation for California Air Resources Board.

What I Don’t Like about the Winix 5500–2

No product under the Sun is 100% perfect and needs zero improvement. And the Winix 5500–2 is no exception. So here are the cons:

1. The washable filter requires cleaning every 14 days. Seriously, who has the time?

2. The device generates ozone, albeit in very small amounts. The good thing is that you can turn the PlasmaWave tech mode off and resolve the issue without affecting the purifier’s overall performance.

As you can see, the cons aren’t strong enough to prevent you from buying this great air purifier for Asthma. Still don’t like the Winix 5500–2? No worries. Why not read other air purifier reviews and see if there’s something you might like better? You can also check out this other great Winix.
