Reviews on Holmes Products HAP422-UC Air Purifier Pleasantly surprised I purchased this air purifier from Wal-Mart for about $60 after putting a smaller Holmes unit in my daughters bedroom. My daughter and I ha...
My Problem
Hildegaard has asthma which may be triggered by an allergy. We aren’t sure exactly what causes her coughing. She coughs when she gets up. She coughs when she comes in from the cold outside. If she exercises, she is a wreck the next day. Her doctor said in addition to giving her steroids, we should consider an air purifier. I’m at my wit’s end trying to keep her coughing at bay and my sanity intact. Why not try this?
What I Tried
I stopped by Wal-Mart after work one day. I saw a number of different air purifiers on the shelf. How much did I want to invest in an idea that might or might not work? I just picked it up and went to the checkout stand. It must have been mismarked. It was somewhere in the neighborhood of $13, clearly under $20.
Speeds/Filters
There are three speeds on this air purifier, low (bedroom setting?); medium (throughout the day); and high (areas with bad problems). A light will come on to indicate the fan is underway. I could feel the breeze from the fan from about 15′ away, across the room. I think a higher setting probably would have blown the loose papers off the coffee table. To release negative ions into the air, turn the second knob and the second light will illuminate. An indicator light will illuminate when it is time to change one of the filters. You should check the filters every few weeks.
The black sponge type filter can be washed in warm soapy water and once it is throughly dry, be put back on the unit. Do NOT reuse the HEPA filter. This needs to be replaced. I cannot tell you the cost on these, as I haven’t replaced them yet.* The HEPA filter should last 3-6 months. Remove the plastic film around the filter before you use it the first time. This can be a little difficult, as well as replacing the plastic grill back on the frame.
Noise
I set it on medium. I quickly got accustomed to the noise. I probably wouldn’t have noticed the low setting. I think the high setting would have been too loud for an ordinary household setting.
The dimensions are about 26″ tall by about 10×7″ oval. There is a grill on the front, along with a black sponge rubber type filter across it. Further to the back, are fan fold filters, rather tightly woven.

I suppose the question that begs to be asked is if it helped Hildegaard with her allergies. I don’t know. About that time, the first hard freeze happened. I thought it helped a bit, but then she started coughing again. I finally took her to her dr. once more, who gave her a shot that should last a month. We have since unplugged this Holmes Air Purifier.
