Best air purifiers and air cleaners for pets, pollen, and more gas 2015

####

We know taking deep breaths is calming and all, and we don’t want to freak you out — but those big gulps of oxygen can contain a lot of harmful dust, pollen, smoke particles, mold spores, and pet dander. Dirty air is easy to overlook because you don’t notice it, but your future self could very well feel the effects. We’re talking asthma, immune system weakening, lung problems, and increased vulnerability to sick building syndrome.

But there is a light at the end of this snot-filled tunnel: Eliminating these airborne particles is the best way to cope with allergies and other respiratory infections — and there’s no better way to trap these pain-in-the-ass irritants and increase air quality than by using an air purifier with a HEPA filter.

Plus, air purifiers are ace when it comes to ridding a space of animal smells like litter boxes and pet beds, as well as clearing the air of smoke stench from cigarettes, pollution, or fires without opening a window. (And no, getting an air freshener is not good enough.)

As you can guess, Amazon is totally on top of the air purifier game. We found the ones with the best customer reviews, and have separated them by price. Whether you need something small to take with you or you’re in the market for an air purifier that can handle the whole house, you’re covered. May the red eye relief be with you. 9Oine Mist Humidifier and Portable USB Ultrasonic Air Purifier — $13.99

Pet parents: We know you love your fur babies, but you can admit that their beds or litter boxes don’t smell the best. The Hamilton Beach 04384 Pet Specialized Air Cleaner is your answer to combatting reeking rooms (and getting rid of pet hair that you constantly see floating in the air). This is due to its 99% HEPA filtration and use of zeolites, or non-toxic absorbent crystals, which are naturally activated when combined with heat and water, and are also being used in new efforts to reduce CO2 emissions. The Hamilton Beach air cleaner is said to be optimal for rooms up to 140 square feet, but numerous customers have mentioned that it can handle larger spaces.

I’m very pleased with these… enough that I bought two for my house and one for my mother’s house! We have one big (mastiff) dog, and a couple small dogs, plus three cats. I placed in the laundry room (where the cat box is) and in the living room (where the dog beds are) and within 48 hours I couldn’t even tell we had pets! My husband also smokes in the house, and we can tell a definite improvement in the air quality and freshness. Highly recommended.

Moving on to the big guns: The GermGaurdian 3-in-1 purifier with HEPA has the best ratings and highest number of customers in the bunch, so yeah, it’s a pretty good contender. This Amazon’s Choice air purifier cleans air with UV-C light technology along with titanium dioxide to kill airborne bacteria, viruses, germs, and mold spores. Though it sits on the floor, it’s slim enough to be tucked in a corner, in between furniture, or somewhere else out of the way.

Love this! This really really cleans the air. It makes my life a lot nicer during allergy season. I can tell the difference. I have a lot of cats and it make my house smells clean. I loved it so much, I bought another. We have a big house and you can tell the difference when they are running. People who visit our home alway say "If you didn’t see the cats you would never know they were there, it doesn’t smell like pets"!!! Awesome!

It’s not the quietest thing in the world on its highest setting, but if you’re anything like me, that white noise could actually be great for drowning out city noise, neighborhood lawnmowers, and more. Overall, the GermGaurdian has a 4.3 out of 5 star rating, purchased by over 8,000 people (whoa). Get it for $149.99 here.

For a little more oomph and widespread coverage, the Honeywell True HEPA Allergen Remover is great for larger rooms up to 465 square feet. With your choice of one of four cleaning modes (germ, general clean, allergen, or turbo), this powerhouse can apparently filter and circulate air in the room five times per hour — and will automatically shut off after the selected amount of time. It can sit on the floor or on a tabletop, which makes it a pretty versatile choice for homes of all sizes.

My chronic allergies and sinusitis have required that I use HEPA air filters in every room of my home. This unit is by far the best and quietest air filter that I have ever owned. Consumer Reports rates this air filter very high and with good reason, because it’s the best and most affordable unit on the market to date. The unit is very simple and offers double filtration, the extra thick charcoal filter is first, followed by the extra thick HEPA filter. This makes it a great space saver that can be placed almost anywhere, especially against a wall.

There are way too many other positive reviews to count, with numerous customers mentioning how quiet this thing is — even on the Turbo setting. Overall, it has a 4.3 out of 5 star rating and has been purchased by over 1,600 people. Get it for $199.99 here.

If you were hoping for a more modern design, the Coway AP-1512HH Mighty Air Purifier is aesthetically pleasing AF. This Amazon’s Choice product looks too clean and will blend right in with any home’s contemporary decor. Called "mighty" for a reason, this puppy features a four-stage filtration system with a 99.7% HEPA efficiency rating (in a space up to 570 square feet). All of that sounds like it would be intense and loud, but this thing is seriously quiet. When it’s done and the built-in air quality monitor hasn’t sensed pollutants in 30 minutes, it’ll turn off for max energy savings.

I have had this purifier for two years now and it is, by far, the best large purchase I have ever made. I’ve noticed a huge difference in my health since buying it and it truly works!! The air quality display is accurate, too! It turns red when it detects smoke, when I vacuum, or even when I spray Febreze; if my cat sits in front of it, it turns purple almost immediately!! I highly recommend this air purifier and will buy another one without hesitation when this one finally goes out.

Another customer put stickers on it and turned it into a giant iPod Nano. (If you do this, send pics.) Overall, the Coway Mighty has a 4.3 out of 5 star rating, purchased by nearly 1,000 people. Get it in black or white here, with prices starting at $229.99.

Meet the granddaddy of all purifiers: The Alen BreatheSmart Customizable Air Purifier can make your indoor air practically as fresh as outdoor air, and is ideal for those who have severe allergies, lung conditions or asthma, or who live in areas with lots of pollution or where forest fires are common. Probably similar to something you’d see the cast of Extreme Makeover: Home Edition put into a house, this puppy provides robust coverage to spaces up to 1,100 square feet. The purifier also comes with built-in air quality monitor and a HEPA-Odorcell filter, best for eliminating lingering diaper, pet, or mold odors. It’s also available in more than a dozen color and finish options, plus there’s also one that’s specifically designed to be painted so you can match it to your room.

These are amazing. My husband has some lung issues. When he was in the hospital for an another issue, he didn’t cough. The first night he was home he started coughing again. So we thought, hospitals have the ultimate in filtrated air. So I found the best air purifiers I could find and bought them. The first night we used them, his cough was much improved. We use them almost 24/7 now and wouldn’t be without them.

The BreatheSmart has a 4.5 overall rating (out of 5), purchased by nearly 400 people. And thanks to the aforementioned color options, even though it will take up a bit of floor space, it can at least blend in with your decor. Prices start at $629, but customers say it’s "worth every dang penny." Get yours here.
