RabbitAir BioGS SPA-421A

We like the fact that it is very silent, consumes very little energy and comes with features you’ll only find on premium air purifiers. We believe this is an excellent buy for those with mild to moderate allergy problem.

AllerAir 4000 Vocarb

If you don’t care about noise, style and ease of use – but need a powerful machine that could help reduce odor, smoke and harmful gases, consider this one. But if you need a balance between the two, keep looking.

AllerAir 5000 Vocarb

What AllerAir has built here is a machine that can clear your everyday airborne contaminants effectively and also controls odor, smoke and gases – better than most commercial machines out there.

If you live in an area where that is a big problem, seriously consider this machine.

Allerair 5000 Exec

Like we said before, the 5000 Exec is just like a rally car. If you want performance – this machine can deliver it. But if you want a machine pleasant enough for your eyes and smart enough to tell you when the filters need replacement, look elsewhere.

Austin Air Healthmate Plus Editor's Rating :

Austin Air Healthmate Plus

Austin Air Healthmate+ is like a car with a very powerful engine. Unfortunately, it lacks many convenient features you’d expect when you buy a machine at this price.

The company takes a great care to add potassium iodide into it’s carbon/zeolite filter to control gases and smoke. It also has 60 feet of true HEPA filter,which is one of the biggest filtration area in a home air purifier.

But while the core is good, we have a few issues with this machine.

Timely Tips

One way of reducing your allergy is by cleaning your home. While you're at it, remember to clean windows, bookshelves, air-cond vents.
