Guest guest Posted February 15, 2006 Report Posted February 15, 2006 How about all the mycotoxins circulating now thru my return going in my new hvac? I worry about that since hvac have some moisture seems those spores will contaminate my new hvac. I did have a hepa filterization sytem added to unit but seems Carl said that will only help 50% which I don't really get if hepa traps 0.3microns. I also have a merve 11 filter inside and I think I should hepa vac and wipe the grid with vinegar every time I change the filter. I have filters in my floor vent registers also. The hvac guy said for me to use the cheap regular filters to make sure I didn't block too much air flow but I want the highest merve filter and using that right now. I wish I could have all my carpet removed too and that would spread more mycotoxins. Can't afford it right now anyhow so just hepa vaccing and hoping it is getting somehthing up but if they are sticky and imbedded in the carpet, I wonder how the vaccum gets them up. I'm thinking about not even putting up new valances on windows since they are just dust collectors and spores flying around will land on the new ones. I wiped down all blinds for now and thru out some. Will replace in future if things ever settle down.

Guest guest Posted February 15, 2006 Report Posted February 15, 2006 -Carpeting is a massive resevoir for contamination-even in a clean place- I am not trying to add to your burden of work- but when I moved into my nice clean rental- it had 2 rooms carpeted- so I bought a hepa vacumn- even with having other people vacumn, and leaving the house for the day, I was sick for three days after vacuming. With permission, I pulled the carpet out of the bedroom, and just painted the chipboard with floor paint and covered the living room floor with plastic-taped around the edges- this more than anything else I did in the last year instantly led to increase health- I cannot advise people strongly enough that carpeting is a sponge for toxin and all kinds of dirt-to live with wall to wall when you are sick is to ask for more sickness -- In , " Rhonda " <rhondaleokitty@...> wrote: > > How about all the mycotoxins circulating now thru my return going in > my new hvac?

Guest guest Posted February 16, 2006 Report Posted February 16, 2006 Rhonda, Sorry if I mislead you so let me clarify. >I did have a hepa > filterization sytem added to unit but seems Carl said that will only > help 50% which I don't really get if hepa traps 0.3microns. I believe I acutally said 1/3 rather than 1/2. Yes, HEPAs filter 99.97% at 0.3 microns -- but only the particles in the air that gets to the HEPA. Add-on HEPA filters on furnaces don't run all the air through the HEPA. Only about 1/3 of the air goes through the HEPA with the other 2/3 thirds straight through the furnace just like it always did. So you need your regular furnace filter. Your MERV 11 was a good choice. The way the HEPA helps is when the blower runs all the time then the air is sequentially filtered, gradually reducing the amount of particles in the air - assuming more isn't being added from other sources. Just like a room purifier does it. Imagine a whole house HEPA on your furnace as a big purifier and you live inside it. > I also > have a merve 11 filter inside Yes, to filter the 2/3 that doesn't go through the HEPA. > I have filters > in my floor vent registers also.

But a MERV 11 plus additional floor vent filters might. Because your ducts were recently replaced and cleaned there won't be contamination past the HEPA and the MERV 11 filters so the vent filters aren't really needed. > I worry about that since hvac have some moisture seems > those spores will contaminate my new hvac. HVAC has moisture only from a humidifier or when the A/C is on. Otherwise any contamination won't be anymore than what would " normally " be there anyway. This does not negate all the work you just did. It's like cleaning shovels full of dirt from a room and then worrying that what tracks in on your shoes will immediately recreate the room full of dirt. Carl Quote
