“These can only be purchased online. Seems like a rip off but as these are " specialized" filters made for our furnace. There is no generic version. we have no choice.”

“The Aprilaire 413 Air Handler filter is excellent for filtration of dust and its longevity. They are a bit expensive, but do an excellent job and are easy to change.”
“the post office dropped the box on my porch it was wet. the filter is cloth like and I had a concern that the damp box would cause the filter to get mildew and mold I should have sent it back it is still in the box”
“If you have a higher-volume HVAC system (i.e. moves more air than typical builder's grade system for typical single family home) and you want something demonstrably better than most stuff you find at Ace Hardware or Walmart, and which doesn't need to be replaced as often, any of the filters in this series are worth a try.In particular if you have a brand new system and/or newly cleaned duct-work (and want to keep it that way), or just moved into a new place and notice a lot of dust and debris in the ducts under or behind the grates, these are a good place to start. Note that because of the cloth-like design, they will stress your fan and motor a bit more, especially always-on variable speed models. So make sure the one you've got is rated for this type of filter otherwise you might end up causing yourself a maintenance headache after a while.For a first run in a new home you will probably want to replace the filter every 2 months until you notice that less material is collecting on it. The rule of thumb I use is when the entire surface is coated in a few mm of gray dust, I change it. It will almost look like a "blanket" overlaid on the filter material. Eventually you should be able to replace this once every 4-6 months, depending on the air quality in your area, the amount of paint dust in your house. If you have really good air quality and don't use the HVAC 12 months a year you might even be able to stretch it to every 6-8 months. Even though they're rated for it I would not leave a filter in for 12 months unless the structure is very clean / has very little dust and traffic from humans and pets. These are definitely not meant to be swapped out every month and are priced accordingly.”
