Media Filter Pads – Low Maintenance And Affordable

Rate this post

Of all the different types of furnace filters available today, media pads are used less often than most of the other types. Media pads are more commonly used by HVAC professionals than home owners. Only about 10 to 15 percent percent of home owners use them and the two biggest reasons for this are availability and awareness.

Media pad filters are very commonly used by HVAC companies where cost and reliability are very important. These companies use huge quantities of these each year. Cost is so important because commercial businesses require three to six filter changes per year depending on environmental conditions. This can add up to thousands of dollars per year.

Media filter dust holding capacity is very high compared to some of the other filter types available. For example, pleated filters are very efficient but lack the holding capacity of the material used in filter pads. Pleated air filters become blocked quite rapidly because it is a single layer of material. Filter pads utilize all of the material in the filter. If dust is not stopped by the first part of the filter it will be stopped as it gets deeper into the filter.

The most common supplier of these filter pads are wholesalers who cater to HVAC companies but most wholesalers will not sell to anyone other than air conditioning and heating contractors. However, they are available from some on line stores.

Available In Two Forms – Pre-cut Change Pads And Bulk Rolls Media

Filter media pads are available in 25 and 20 inch widths and can usually be cut to any required length. These pre-cut filters are available to home owners on line or from your local contractor.

Rolls of media are available in one hundred foot rolls of 20 or 25 inch widths and are cut to fit into a filter holding frame. These filter frames are usually made of aluminum and are used many times over, usually lasting for the life of the air conditioner or furnace.

When it comes to cost these are probably among the best available to home owners. The big advantage of these filters over electrostatic air filters is they do not have to be rinsed clean every few months, just change the filter pad and reinstall the frame with a new pad.

Most pleated air filters are more efficient than media filter pads but you have to be more conscientious about how often you change them. These filters do not have as much dust holding capacity as filter pads because all of the dust they stop collects on the surface of the filter. This leads to greater resistance to air flow in less time.

Media Pads are usually made of polyester or some other synthetic material and can be used in all brands of air conditioners including Trane, Carrier, Lennox, Ruud, American Standard and all others. They will also replace any other brand of air conditioner filter including Honeywell, 3M and all others.

    We currently use the BoAir precut media filters. However we still suffer from allergies. Do you think the boair 5 stage electrostatic filter would be more effective?

      Although electrostatic filters and media pads are great for applications where some dust is not an issue I don’t recommend using them if you suffer from allergies. At best electrostatic filters only have about a MERV 8 rating and media pads only have about a MERV 5 rating. If you have allergy concerns I would recommend a pleated filter with a MERV 12 rating or higher. These filters will capture smaller dust particles and provide cleaner air. Although the electrostatic filter is a bit better than pads your best bet is to go with pleated filters.
