{"title":"Filter Racks \u0026 Cabinets","description":"\u003cp\u003eA filter rack or filter cabinet is the housing that holds your air filter in the return-air path and seals it against the duct so all the return air is forced through the media instead of slipping around it. The cabinet version is a larger enclosure — often for a media or high-capacity filter — that mounts at the blower or return and gives the filter a proper, gasketed seat.\u003c\/p\u003e\u003ch3\u003eWhen you need one\u003c\/h3\u003e\u003cp\u003eRather than failing in a dramatic way, these parts come up when you're building or improving a system. You'll want a rack or cabinet when you're setting up a new air handler or furnace, converting from a flimsy slot filter to a sealed media cabinet for better filtration, replacing a rusted or bent rack that no longer seals, or standardizing on a filter size that's easier to buy and change. A well-sealed rack is also the fix when dust is bypassing a loose filter and dirtying the coil and blower.\u003c\/p\u003e\u003ch3\u003eHow to choose\u003c\/h3\u003e\u003cp\u003eTwo things decide the fit. Match the filter size — the nominal dimensions of the filter the housing is built to hold (length, width, and thickness, such as a 1-inch versus a 4- or 5-inch media slot) — and the orientation, meaning how the rack mounts and which way the filter loads: horizontal versus vertical, and bottom-, side-, or end-access to suit the space around your equipment.\u003c\/p\u003e\u003cp\u003eThink about filter availability while you're choosing, since the rack locks you into a size, and consider pairing it with a UV light if you're upgrading air quality. Check the dimensions of your existing filter opening and any model number on the current rack before ordering, so the new housing lines up with your ductwork.\u003c\/p\u003e","products":[],"url":"https:\/\/nationalhvacparts.com\/collections\/filter-racks-cabinets.oembed","provider":"National HVAC Parts","version":"1.0","type":"link"}
