Guest guest Posted February 18, 2005 Report Share Posted February 18, 2005 Hi, Please read up on all info about the filtering systems you choose. Ion vs HEPA vs heat. Lots of info. I use an ION filter (no filter to replace) you need to be aware that each filter has it's own hazards. Some people are allergic to the charcoal in some, others are worried about the ionizer destroying their lungs.Check the capacity to clean of each. no sense getting one that only does small rooms if you need a large house done. I have a special IQ cleaner at work that has a 4 stage filter from IQ air. I work in an enviornment with all kinds of issues. So again really read up on them before buying.

Guest guest Posted February 18, 2005 Report Share Posted February 18, 2005 May I suggest that you only buy 1 of these air puifiers (ion or ozone generating) at first as some people find any type of ozone odor offensive and they can actually cause respitory problems in some people. If you use an Ionizing purifier I believe they say your particles are weighted down with the extra ions, and that you can collect them later with your vacuum cleaner or other cleaning device. I certainly hope that your cleaning device has a filtering sytem (such as hepa bags) that will not just blow the particles back into the room again. Also remember that if your air is not being returned to the filtering device you are not cleaning your air you are only moving it around, air cleaners need to be left on. Filters: HEPA: High efficiency particulate air (HEPA) filter is 99.97 percent efficient for 0.3 micron particulates when measured with Military Standard 282 DOP test. DOP: Hospital-grade DOP filter is 95 percent efficient for 0.3 micron particulates when measured with Military Standard 282 DOP test. CPZ: ( Carbon, Permeolite, and Zeolite ) Sorbent modules . Adsorbs higher molecular weight hydrocarbons and oxides acid gases and lower molecular weight hydrocarbons. Electronic Air Cleaners: Electronic air cleaners work by having the particles pass by ionizing wires which charge the particles. After this they will pass by the collector plates. Every other collector plate is also charged and pushes the charged particle to the grounded plates. These charged particles are then held on the plates until they are washed off.

Guest guest Posted November 2, 2007 Report Share Posted November 2, 2007 Thank you very much for the input. I'm pretty much sold on the HealthPro Plus, even though it's going to cost more and the filters are very expensive. I wish I could afford to remediate or move, but both are impossible now. The HPP does have the extra HEGA filter that removes gases and odors and their HEPA filter removes particles as small as .003 microns. The brand was also used in Hong Kong hospitals in the SARS wards. No UV, but I've since been told that the lights burn out quickly and can also damage other parts of the purifier. When I get the unit, will give you feedback on it. Barth --- L> , L> HEPA filters will remove the physically larger particles from the air.

Some research indicates that smaller particles have higher L> toxicity by weight, I think, so thats something to be concerned about!

L> But they might also be dangerous in the sense that they might induce in L> people who are using them a false sense of security in a dangerous L> situation. If you keep that in mind, you'll be better off in the long run. L> As far as UV light, honestly, I don't know UV light's effect on mycotoxins.
