"NO"... meaning it would be much less restrictive... think I decided to just buy 12" x 30" x 4" filters. I can pound out the lip that holds the 1" filter, so a 4" filter can "slide by". Then just...

I moved into a new house that has 2 room returns (with 1" filters), one 12" x 30" and one 20" x 30". After trying to find actual dimensions on the 4" Honeywell 1" replacements mentioned in this...

Had a gauge at my old house, need to go out and get another. What's a good limit (for filter change) for a 4 Ton Carrier AH? Maybe 1.0"?

I saw that info Rhino.... not sure about that "assembled height and depth", doesn't seem to jive, pretty sure it's 25" x 20" (or slightly less), that's easy to measure. None of the other numbers...

It's been a while... I still see many familiar names. I've been using Honeywell 4x20x25 Merv 10 filters (FC100A1037) for a while and started searching for a new source. I noticed Home Depot carries...

I plan on calling a tech if it trips again. On the outdoor panel I have a "AC" breaker, a 30A and 60A both labeled "Furnace". The "60A "Furnace" is what tripped. My "guess" is it got cold real...

Outdoor in main breaker box. My Thermostat was "blank", so pretty much cut power to anything AC related.

I have a Carrier Heat pump, about 2 years old (new home). Yesterday the main breaker tripped. After wondering why the house was 20 degrees below set point I discovered that problem, I reset it and...

rh below 40%! Isn't that a good thing? Interesting way to "contrrol" humidity. I've heard the 1"ers clog in less than month (or week, or day)... hopefully at 4" they are more like the...

I bought a new house that had 1" return filters... I had a Honeywell 4-3/8" filter (merv 10 I believe) installed at the AC unit in the attic, and removed the 1" filters. Doesn't seem to be half the...

Here's a shot of the return grills:

I constructed the return plenum before I had the new AC unit installed. It is green sheetrock, caulked at all...

Very "cool" photo. The return has 12" from 2nd floor AND 8" x 24" time 2 from 1st floor (on 2 sides of the 14" x 36" x 40" plenum). Air flow is under 650 cfm 90% of the time, so there's plenty of...

I think I'll evelate myself to 'supreme hypochondriac' after reading that article....

The AH is sitting on a "standard" 20x25" Carrier EZ-Flex filter - normally Merv-10, I have a Honeywell Merv-13...

OK, here's my current set-up:

The SanteFe use to rest on that shelf (I didn't have the aircleaner in that area at the time). The 8" and 6" went...

I'll take some pictures tonight of the Soleus arrangement. It is where I use to have the SanteFe. On a shelf (about 3' high) in a laundry area (so it could drain to the washer drain). I do not...

It was very easy to duct some outside air to the Soleus (via a separate HEPA filter as described above). I have had the SanteFe for 2 years, changed the 2" filter every 3-6 months with the same...

The problem I found with the Sante Fe running the fan is it cycles the compressor VERY often, not allowing anything to dry out. If there was a timer that turned the fan on 4 hours a day, the...

Not sure if it's the cinder block wall or the SanteFe... but the SanteFe had to "catch it" from somewhere. I believe the last sample that you just commented on was from the SanteFe last time I...

Wonder how much moisture an 8' x 35' cinder block wall up against a large hill lets in... 2' of pea gravel drainage, but probably 75% full of soil/moisture after 25 years (and probably cracks). My...

Unless there are already trillions in the house. Got to be at least half billion in the Sante Fe ;o) Want me to send it to you so you can count them?

Yeah, I think I decided to put a duct fan...

That's what the dehumidifier is for! ;o)

I know... but with 1 AC and a 3 story house, it's much more comfortable from floor to floor with the fan going. And I'm hoping the 5" Merv 13 filter is...

No pets, no kids at home. I've had many theories over time; might be some kind of "in"-gassing, "seepage" of some sort through the cinder block wall or slab (insecticide, bad water, bad dirt...). ...

Intake 30-50 CFM outside air (6" duct), 150-200 cfm from second floor (8" duct), plus maybe 25 cfm from laundry room where SanteFe is located (four 2" holes above filter). Exhaust is 50% into...

I had a plumbing leak (like 4-5 years ago), and had the house tested, and went through remediation. New AC, new ducts, "clean" bill of health... They obviously did not get it all, but then again...

I assume by "this system does not create dust" you're refering to the SanteFe... It's inlet is a 6" outdoor vent (6' long duct, very clean, Hepa filter on outside vent), and a 8" metal duct from the...
