20 x 25 x 4 Air Filters for AC/Furnace.. - decocritter - 11-27-2007

I have a "special" filter that is supposed to last a year, but they don't seem to. What are they supposed to look like when they are too dirty? I want to change them properly, but not overdo it.

Trion Air Bear - which no one seems to sell locally. Also for some reason these things bend when trying to get them in the holder.

I just bought a Filtrete Brand

They are now $29.00 at Lowes and HD, They used to be around $15-20.

I had a special similar filter for my HEPA deal on my A/C back in Louisiana, pre-Katrina. I used to order them online; a lot cheaper than local and they delivered quickly. And for the life of me I can't remember the name or find a link (well, it was over two years ago...).

Find the part number on the filter and then put that in a Google search. If you don't find anything at first, put in that part number along with the word filter (e.g., "012345-ABC-678" + filter) and you'll likely find them.

FWIW, I think I changed mine about four to eight times a year, if not more often. They weren't cheap, or at least they weren't as cheap as even the high-filter types you get for a regular A/C filter at the local store (i.e., anywhere from $5 to $25). But we were an active house and we kicked up a lot of dust and dander, apparently, so it got changed more often.

How do I know which direction to put the filter? There is an arrow on the filter (says air flow), but not on the holder.

I am not sure which direction the air flows through it.

On my installation the furnance is on the left, the air filter holder next, then a big tin box is next.

Air flow is towards the furnace.

Or to the left in your instance.

I ordered a case from these folks last year:
http://www.aafilters.com/cgi-bin/quikstore.cgi?search=yes&detail=yes&product=170-102-000&category=&keywords=&hits_seen=&page=search.html&exact_match=yes
20x25x4, $78.30 for a case of 6.
The order came quickly and the quality was better than expected for the price.

I bought a Filtrete one at Lowes. It was $29.00. I offered them the $20 they used to sell them for. They countered at $21 plus tax. I took it.

I have never bargained in a retail establishment. I watched a morning show where they said to be very nice and try.

I nicely told them, I did not feel like going over to Home Depot (which was out).

I did not realize they were so competitive.

I noticed the Merv factor has gone up on some of these filters. My original was 8.

The new one is 11, some on the net are higher.

Follow my link and place an order! These suckers should be changed every three months, at least.

whoa! great prices, and with free shipping. I think i will get a case for my furnace. i run my fan on low 24/7. Really cuts down on dusting the house, and evens out the heat/cool.
