SVI's Type III MERV 14-15 retrofit Kit

is a super-easy retrofit that installs in less than five minutes. You can quickly replace the usual home made polyester fluff filter setup. The kit uses a modified air intake grill, a  new airtight filter holder and a new cone-shaped filter cartridge. Includes four stainless steel screws and plastic mollies. In most cases, the stainless steel screws will  install into the existing screw holes and existing plastic mollies. More than likely, you can completely install the Type III filter retrofit kit in about the same amount of time it takes to service the home made filter a single time.
