Room Air Filter - recommendations to buy

[tspisak]

I just started using CPAP and when I take off my mask in the morning its very obvious that I have a lot of dust in the air (baseboard heat turns on automatically in the morning). Anyone have suggestions of a good room air filter?

I put duct tape over the blue light.

This is the one that I've used (though mine is an older version):

I got the Whirlpool AP51030K because it was #1 in Consumer Report's reviews. It only got a 'Good' rating on Noise on 'High' speed however; it is a tad loud, especially on its higher settings. It got a 'Very Good' rating on Noise at its low speed setting, which is what I usually keep it at.

I find the CPAP noise more annoying than the filter; at least the filter's white noise is constant. The CPAP's noise changes on inspiration/expiration which keeps me up sometimes. The air filter downs out the CPAP so I find it easier to sleep with the air filter on

I've noticed since running the air filter the filters on my CPAP machine essentially look unused.. I still change the filters on my CPAP in case there is microscopic stuff trapped in them, but there are no more visible particulates trapped in them.

In the posts above, there are two different technological approaches to air filtration: HEPA, which forces the air through a filter, and electrostatic which precipitates particles by giving them a a static charge.

Can anyone here offer a rundown on which is better?

HEPA by a mile. There is still controversy over whether the other does anything at all.

Electrostatic is good at making ozone, a lung irritant. So it does that

I've not also seen any compelling evidence that the fanless electrostatic models or ones with a small fan can even move enough air to process the air in a room.

Electrostatic has worked for me for the past 8 years. Never had an issue with them. Never had to by a filter either. It does create dust on your furniture but that's why we dust. I dust with a Dyson vacuum and a lemon oil rag for shine.

This question turned out to be more interesting than I expected. The following link

http://en.wikipedia.org/wiki/Air_ioniser

discussed ionizing air purifiers, which are not, as I had supposed, electrostatic. I checked Consumer Reports and they did recommend one ionizing purifier. It uses a fan to move air. It was down the list of products listed by overall quality, however.

I was interested to find there is evidence that ionizers are effective for Seasonal Affective Disorder. if you follow Wikipedia's links you will eventually find this, from a controlled study at Columbia U:

Conclusions: Bright light and high-density negative air ionization both appear to act as specific antidepressants in patients with seasonal affective disorder. Whether clinical improvement would be further enhanced by their use in combination, or as adjuvants to medication, awaits investigation.

I have a Kenmore Airpurifier that they don't sell anymore, but its similar to the Winix 9000. Except that I doesn't have the light sensor/auto night mode (and I like it that way, because I keep my bedroom dark all the time).

And, the odor sensor seems to work...because it'll rev up during the night when I get rid of air that I've swallowed.

Another possibility would be a room humidifier, if you need or can use more humidity in your room. Water film is a good filter as it catches the particles and carries them down into the reservoir. Water is used to stop paint particles from escaping paint booths so we know it works. Whether a room humidifier would do the job as good as you need I don't know. But I think it's worth considering, for a few minutes anyway!
