What type of filter do you use for your Central AC's intake?

[CorCentral]

What type/brand of filter do you use for your Central AC and how often do you change it?

I use a 3M Micro Allergen 1000 (3mth filter) and change it every 2mths because I have cats. (size is 24x30x1)
I used to use those cheap blue fiberglass ones, but after my wife and I got cats, I've always bought the better filters.

I use the same filter, but because of seasonal allergies.

*shrugs* I'm too lazy to look at that. I'll leave things like those up to my landlord.

Our filter is one of those electronic static zappy things.

I use the super cheap ones and change them once a month. AFAIK there is no "intake" on central air, it just moves the air in the house. It would be really inefficient to try and take outside air and cool it.

Its still an intake into the furnace itself.

You know what I mean, the air that passes through the filter is an intake!

There most certainly is an intake. An air handling unit has a supply and return opening which is attached to the building duct system. Ducts with a positive pressure are generally classified as the supply side and ducts/plenums with negative pressure returns.

On residential units, the filter is usually in a slot just below where the return air plenum is attached.

Rectangle shaped one with some plasticy stuff. Dunno what brand or model. It has cardboard along the edges.

Spaceguard competitor! Those along with electrostatic precipitators work very well in theory. Of course differential pressure and lack of upkeep (both types respectively) notwithstanding they are attached to a clunky plumbing of sorts held together with a leaky fastening system of slips and drives allowing dust and allergens to successfully bypass these filters. Many residences also use the space between floorboards and wall studs with sheet metal panning laid out to complete the "seal" which leaks more than three screen doors on a submarine.

I don't care if it saves $$, every 6 weeks is just too much work.

A mouse?

Sorry, I couldn't resist!
