Stretch how much more restrictive is a pleated filter and why? Which size
1", 2", 4", HEPA. Which ones are you speaking of being more restrictive.
How long should they last, when are they at peak performance. Is there a
way to use an electrostatic without it becoming too restrictive. What is
the real problem if the use of a pleated filter is too restrictive for a
system. What is the surface area of filtration with a pleated, vs a non
pleated. How does that extra surface arera help or hinder the filtration.
How much dirt does a standard $.50 filter stop or allow to get to the coil
to get either stuck in the coil or back into the air stream.
I apologize for asking so many tough but pointed question of you but you
should not be downing products that are going to help people, when you show
a limited amount of knowledge about filtration ,but are portraying a
Pleated filters are alot healthier than any standard filter. An
electrostatic is great but must be cleaned about every 3-4 weeks to reduce
restrictions of air flow. I have seen (almost always) a 4" pleat as in a
Honeywell or Aprilaire Media 4-6" filter laast a year. 1" good pleats
should last 6 months. Now if you are having construction around, or have
shedding animals these times are greatly reduced. I would never have an
electronic air cleaner in my home. Unless they are cleaned every three
weeks they are useless. I have installed hundreds of Media Air Cleaners in
properly designed systems with proper air flow. If you are not willing to
allow your contractor to do the job right, or if you deal with contractors
that aren't educated enough to know how things are supposed to be you will
In terms of Ultra-violet air purification systems they are great if you are
alergy prone or you have a mold, mildew, amongst a bunch of other things
they destroy. The do create Ozone, but there are a couple that kill the
ozone before it enters the air stream. We only use Sanuvox, and install
them in the return duct before the media air cleaner. My customers rave
about this set-up and have referred me to numerous other people with alergy
problems. My doctor is referring custoemrs with central systems to me also.
You guys are not completely informed, and I guess this is the main way you
are trying to be informed, through the usenet. There are alot more
competent sources. Even on the net you can get informed, but there are
idiots spewing garbage out there too.
I really apologize for coming into this thread without reading the earlier
replys, I usually just read what the HVAC guys have to say. So I apologize
for this long rant
