It depends on the filter on how you clean a reusable filter.
- For our standard metal mesh filter there are two different ways depending on how dirty the filter is. First, you can brush or vacuum the dust off the air entry side. The other option is power wash or use a garden hose. When you wash the filter with water you need to backwash the filer. Spray the power washer or hose on the air exit side. Make sure the filter is dry before replacing it back into the system. Apply our filter spray on the air entry side when the filter is dry and place back into the unit.
- Infinite Gold 8 filter needs to be cleaned by a garden hose or in a sink. It needs to be back washed as well. Spray water into air exit side with the drain holes on the opposite side. Make sure the filter is dry before replacing it back into the system. It would not be a bad idea to buy an extra pleat and place it into the system while The Infinite Gold 8 is drying.
- Grease filters can be washed multiple ways. It depends on how much use this filter receives. A mild degreaser can do the trick. Or can be power washed with soap and water.
Measure your filter from corner to corner of the frame. Filters are measured by width x height x depth. Standard sizes are considered nominal sizes. Nominal sizes are undersized by either ½” or 3/8”. This will be indicated when ordering. Thicknesses are nominal sizes as well. Disposable filters thicknesses are undersized by ¼” and permanent thickness are undersized by 1/8”. 2” grease filters are 1 13/16” thick. If your size is not considered a standard size we will need the exact measurement. The manufacturer goes by exact sizes if they are not listed as a standard size. Grease filters need to be ordered with the correct vertical size. If they are ordered with the wrong vertical size the filtration and will not drain correctly.
MERV stands for Minimum Efficiency Reporting Value. This rating system was designed by ASHRAE to standardize and simplify filter efficiencies. We recommend at least a MERV 8 in your house. A higher MERV efficiency does not mean it is better. A higher MERV rating may incur a higher initial resistance. A low initial resistance means less energy being used. This is why we only sell MERV 8 filters for your house.
There is no guarantee on a filter. It all depends on the environment and application. We recommend changing a pleated filter every 90 days and cleaning your washable filter every 30-90 days depending on the application. This will ensure to get the most out of your filter.
It is very important to change your filter at the recommended life expectancy. The main cost of a filter is not the price of the filter itself, it is the energy cost. If you do not change out your filter the blower is have to work twice as hard on a dirty filter. A clean air filter will help ensure that your system is running efficiently and use less energy. Doing this will save you money in the long run.
