Holmes Products HAP240 Air Purifier

Pros: Small, relatively quiet, does its job effectively
Cons: After a few months of use, can't find replacement filters anywhere

I have a home office (grapic design) in an upstairs bedroom in a 20-yr old tudor style home. We bought the home about 1.5 yrs ago and although the carpeting is in pretty good condition and has been well taken care of, I'm sure it's the original stuff. ...

Pros: Small, cheap, and does a decent job in a relatively large room.
Cons: Does not filter nearly as much as more expensive models.

Living in an apartment that has windows only on one side, I have problems with ventilation even during the summer. Now that winter has hit Ohio, I needed something to keep the indoor air breathable. So being a good American, I headed to Wal-Mart and ...

Pros: Simple. Keeps going and going; low cost for the unit, and low cost replacement filters.
Cons: Small filtering capability. In its old age, mine has grown louder at the higher speeds.

I've had this product now for about 4 years. It is rather small, so it won't handle a whole room, but it's fine for what I use it for: it sits next to my bed where it keeps relatively clean air circulating directly over where I sleep. The unit ...

Pros: Price, durability
Cons: Filters seem expensive

Let me tell you my history here: I used to work as a mud-logger in the oil field, and what this means for this story is that I worked in a 12'x 30' trailer with men that smoked. And when I say "smoked", what I mean is at least five packs per day of the ...

Pros: Work quietly, efficiently, lessens odors in the air like pet or smoke.
Cons: Filters may be difficult to find locally, ionizer feature cannot be used with asthmatics

We received this air purifier as a gift from my mother some years ago. We were impressed with how quiet it was. Also we liked how there was an ionizer for odor control and ease particle collection. We were amazed at how much dust, dirt and hair it ...

Pros: Cheap, Filters lasts 6 months.
Cons: Motor dies after 3 years.

HAD OLD WHITE MODEL IN 3 ROOMS. 2 of 3 Stopped working both 3 years after purchase 2 weeks apart. I figure that is the life of the motor. Since I had a few spare filters I opted to buy same model again which has been upgraded to silver color and slightly different outside design. Will report how long this model lasts. Hopefully longer than 3 years!
