Guest guest Posted November 19, 2005 Report Share Posted November 19, 2005 So you're saying this Friedrich is not catching any mold spores, right? Loni pwcwg325 <pwcwg325@...> wrote: Right, thats the pre-filter. That catchs all the stuff you can see in the air(dust and particles. The contaminants caught is this pre- filter are larger particles which your body defenses are made to handle. I am speaking of the smaller particles which make up 85% of what you breathe. These particles are .3 micron in size and get deep into your lung tissue. HEPA is 99.9% effective at capturing these particles and becomes more effective as the particle size becomes larger (pet dander, dust, tobacco smoke, odors) and other filters can not come close. The white dust is mostly seen in homes that have this electrostatic technology connected to their duct system. The dust forms when the partcles are charged but dont stick to the metalic plates. The charge makes the partcles heavy and fall into the carpets/furniture. Thus, the home owner will see an increase in dust. > > > > > In a message dated 11/15/2005 12:22:17 AM Pacific Standard > > Time, > > > > > grimes@h... writes: > > > > > > > > > > KC and Sharon, > > > > > > > > > > At the risk of sounding like a traitor, don't throw the > baby > > > out with > > > > > the bathwater.

Guest guest Posted November 19, 2005 Report Share Posted November 19, 2005 I am sure the metalic plates are catching 'some' mold spores but the prefilter is not catching mold spores. Ionic and electrostatic filters do not come close to HEPA filtration. HEPA is recommended by Homeland Security as a #1 rated contamination barrier. www.ready.gov Consider a air purifier, with a HEPA filter, to help remove contaminants from the room where you are sheltering. These highly efficient filters have small sieves that can capture very tiny particles, including some biological agents. Once trapped within a HEPA filter contaminants cannot get into your body and make you sick. While these filters are excellent at filtering dander, dust, molds, smoke, biological agents and other contaminants, they will not stop chemical gases. Some people, particularly those with severe allergies and asthma, use HEPA filters in masks, portable air purifiers as well as in larger home or industrial models to continuously filter the air. > > > > > > In a message dated 11/15/2005 12:22:17 AM Pacific Standard > > > Time, > > > > > > grimes@h... writes: > > > > > > > > > > > > KC and Sharon, > > > > > > > > > > > > At the risk of sounding like a traitor, don't throw the > > baby > > > > out with > > > > > > the bathwater.

Guest guest Posted November 19, 2005 Report Share Posted November 19, 2005 Wayne, As you know, or I hope you know, I'm a big proponent of HEPA. However, they do have limitations and won't clean all the air in your house - even the forced air ones running all the time. The reason is that they act like a " gate " which means they can remove particles only from the air that actually goes through the filter. Because not all the air in the room will go through the HEPA it won't clean all the air in the whole room or the whole house. Only part of the air most of the time. Yes, I know you can design them to get 4-8-12 or more air exchanges per hour. But that is a measure of the amount of air flow rate, not the amount of the total air that is filtered. Some of the air is repetitively recirculated and some isn't filtered at all. Although the part that is recirculated through the HEPA is very very clean the air on the far side of the room or under the bed with the dust bunnies isn't cleaned at all. 99.97% removal at 0.3 microns if fantastic and it is true, but it applies only to the air that actually goes through the " gate. " It does not mean that we can expect 99.97% of all particles in the air in the room will be removed from the room. That's why surface cleaning is most important. If the surfaces aren't clean then the air movement from the HEPA (and other things) disturbs the settled particles putting them back into the air again. But not necessarily into the HEPA. HEPA is fantastic and necessary, but it doesn't replace Merry Maids. It doesn't remove sources. It gets what's left over in some of the air after the surface cleaning is finished and helps keep up with the air that comes in through the door. And with the dog. And us.

Guest guest Posted November 19, 2005 Report Share Posted November 19, 2005 This corresponds with my experience, both in the filter (which, by the way, some fungi and/or mycotixins are smaller than .3 microns) and in the cleaning. Simply mopping a floor does soooo much for how I feel, even if I am too wiped out to do ALL the dusting at the same time. And wet dusting is better than dry, it keeps the dust out of the air. > > Wayne, > > As you know, or I hope you know, I'm a big proponent of HEPA. > However, they do have limitations and won't clean all the air in your > house - even the forced air ones running all the time.

Guest guest Posted November 19, 2005 Report Share Posted November 19, 2005 Carl, I 120% agree with you. The basics like cleaning your home will help the most. It is very true that the only air which is cleaned is the air that is moved through the filter. This is a truth for all filters on the market. Just some are better than others - HEPA.

Guest guest Posted November 19, 2005 Report Share Posted November 19, 2005 I agree that there are particles smaller than .03. EPA standards state that 85% of the particles in the air are .3 microns. Nothing does more than a clean home.
