A dehumidifier has an air filter which functions to remove dust particles from the air before the air passes through the coils. By doing so, coils are protected from wear and tear and clean pure dry air is reemitted into the environment. Over time, filters can build up a lot of dust and debris and if not cleaned regularly, will affect not only the efficiency of your unit but also the quality of air it reproduces.

Air filters come in two types – washable filters and replaceable or disposable filters.

Washable filters save you money in the long run as long if you maintain them correctly and regularly. They can easily be cleaned by either hosing them down or vacuuming. Consider also disinfecting them monthly to prevent the growth of mold and bacteria.

Replaceable or disposable filters can be thrown out and replaced with a new disposable filter. If the dehumidifier is running constantly it will be a good idea to change it every month or more often if it is running in a dusty environment. These filters will not cost you a lot of money and a lot of the time they can be purchased at the same place you buy your household air conditioning filters.

Check the instruction manual of your unit to see how often your manufacturer recommends changing or cleaning your filter. As a general rule of thumb, you need to check them every month or so to determine if they need to replaced or cleaned sooner. This is especially important in very humid conditions as bacteria and mold tend to breed on the filter and can infect the air released into your home.

Replacing or cleaning your filter is quite simple. Remove the air filter from the unit and examine it to see whether it needs a change or clean. For washable filters, wash them down with a water hose, shake off as much excess moisture as possible and leave to air dry completely. If you need to use it immediately you can always blow it off with a leaf blower or simply have a spare and rotate them.  If it is not too soiled, then vacuuming it will do the job just fine. For disposable filters, simply throw away the soiled filter and get the new one ready for installation.

While waiting for your filter to dry, give your dehumidifier a total clean. Clean all coils inside the dehumidifier and brush off any build-up of contaminant. Next, clean the blades of the fan with a damp cloth to remove all dust and particle build-up. Take this opportunity to also inspect all parts to make sure they are all operational and that there is no visible damage. Reattach all parts before turning it back on.

Cleaning your dehumidifier and its filter helps it perform better and last longer. It is important to maintain your unit once or twice a month. A clean filter will remove dust and other particles from the air more efficiently and help the unit performing at its best. In addition, regular maintenance will make it work less hard and use less energy; and as a result can save you in energy costs.
