Comments about Aprilaire Aprilaire Model 4400 Media Air Cleaner with Electronic Control:
The Aprilaire 4400 is a great product, it increased my CFM's by about 20 Percent over the regular pleated filters as this unit has such deep pleats (about 5 inches).Cleans the air pretty good, I would have had to change a filter by now and this one is good for 6-12 months (depending on usage).The remote located display/control is great, I am not happy the light on the display is on 24/7 but the functions on it are fantastic and you can mount it anywhere you wish (within reason).Overall I am very happy with the filter unit, the price of replacement filters are also fairly cheap compared to a regular pleated filter, regular filter[$] replace every month would be around $102.00 a year, replace one of these for about $28.00 a year!Please bear in mind, if you are a normal home owner without any HVAC experience, leave the install to a pro, unless you have no return duct to fool with.The choice for me was clear, its a great product and of course iaqsource had the answers to my question, would bye from you all again!.Many Thanks.
