Cheap Air Purifiers

Air Purifer
Product as described. Fast delivery. Works really well. Bought as a gift for my husband and he loves it. You can tell it works by seeing less particles in the air and breathing is easier.

Not working after two years?
I've had this unit for about 2 years now. A couple of days ago some smoke from my neighbors grill blew in through my windows. I shut them and turned the air purifier on high. Four hours later the room was still full of smoke. I reopened the windows since my neighbor had finished and the smoke cleared the room soon after.

I have had the unit running round the clock for about 1.5 years, before that I used it sporadically. I really don't know if it ever made a difference or it just stopped working after using it approx two years. I've replaced the carbon filter and vacuumed the main filter as needed.

According to the review of a slightly different model (the 50250) at [...]:

"Permanent HEPA filters will need to be replaced eventually, since multiple vacuuming does degrade performance.

Lifetime is a brand name, not a guarantee."

Darnit, now why did I vacuum that thing?? I guess the "lifetime" hepa filter has reached end of life already??

It does work great as white noise to block out my neighbor's constantly barking dog though. Basically like a loud fan.

Honeywell Air Purifier
I purchased the Honeywell 50150 air purifier and was pleased with the price, and prompt shipping. The product works great except for one thing. Honeywell put a light on the dial, which they never had before, and it is so bright it woke me up at night. I have to try and cover it now to block the light. However, for someone who wants a night light and an air purifier, it's perfect. For me, I think they're unnecessary and hope Honeywell removes them.

Ruined my home with charcoal dust!
I purchased this "air purifier" from a local retailer with the thought it would clean the air in my home. After the first week of using the product I began to notice a fine black dust around the rooms I was using it in. The BLACK DUST problem became worse and as it turns out it was from the carbon(charcoal) filter in this air purifier. The unit blows (exhaust) air straight up--about like a box fan on "High" setting. It does not clean off very easy as the dust particles are so fine and now I must repaint the rooms I used this in. I am returning this to the retailer tomorrow!

Great value for the size
If you wake up in the morning with a runny nose, itchy and swollen eyes, or experience frequent sneezing and wheezing, you may be reacting to airborne contaminants. Indoor air is loaded with microscopic dust mite allergen, animal dander, room dust, mold spores, bacteria, viruses and more. These contaminants all contribute to poor indoor air quality which is ranked among the top five environmental risks to public health. And because modern homes and offices are built to airtight specifications to conserve energy, airborne particles just remain in the air with nowhere else to go. No wonder your system is on overload, but a True HEPA Air Cleaner can help! HEPA filters remove 99.97% of airborne particles down to .3 microns. Plus, independent lab tests have shown that the Honeywell 50150 helps reduce airborne germs, bacteria, mold spores and fungus with up to 100% efficiency.*
A survey conducted by Riter Research found that, of physicians that recommended air cleaners, 93% consider HEPA filtration to be very effective and the majority of those physicians recommend Honeywell enviracaire specifically.

The 50150 Model features 360 degree air intake with updraft clean air exhaust, a 3-speed motor, and a Permanent HEPA Filter. The Intelli-Check electronic filter monitor reminds you when to clean** the HEPA filter and replace the pre-filter. The 50150 is fairly portable with a top hand grip and weighs 17 lbs. The unit does not require assembly and the filters come installed, just plug it in and start breathing clean air tonight. This unit is great for a medium bedroom or office and is rated for a 15' x 15' room
