People are becoming more aware of the importance of better air quality indoors. It is inevitable that even indoors there are dust and allergens around the rooms. It has been a must in most developed countries to install air filters in their home and businesses. But prices of the air filter products can cost so much and may not be affordable for everyone. There are some ways to save yourself from spending too much, and one way is it make your own air filter at home. The basic elements of the air filters are available and way cheaper than buying a brand new air filter.

Steps in Making Your Air Filter

Step 1: Gathering Your Materials

You will need the following:

  • PVC tubing around a foot of 3-inch diameter
  • Computer fan which is also 3-inch in diameter
  • An adapter (AC or DC)
  • Toggle switch
  • Hose clamp
  • Filter for the air conditioner in the room
  • Tools needed are: drill, iron, solder, glue gun and glue sticks

Step 2: Preparation

Once all the materials and tools are ready, it is now time to start making an air filter. Drill 2 holes (small) from the wires of the adapter and the fan. Holes should be on top to have room enough for the fan to be installed. Drill another hole, this time a large one, in between the two other small holes; it is where you will put the toggle switch.

Step 3: AssembleAll the Part in Their Specific Location

Twist and solder the negative wires together. And do the same thing with the positive wires to the toggle switch. Use the glue gun to glue and cover the holes where the wires are passed through and also around the toggle switch. Covering it with glue from your glue gun will form an air tight seal. After sealing all the holes, place the fan on the top. It should be in the center so that the air will flow going away from the pipe. Once it’s placed, glue the corners and seal it around the edges of the pipe and fan.

Step 4: Put Together the Filter

Now it is time to put together the filter. It is usually in large sheets. You can cut it and fold into squares and make a layer thick enough for the filtration. Place it above the pipe which is on the other side of the fan. Once placed on top, secure it with the hose clamp. You need to tighten it and trim the excess.

Step 5: It’s All Done

You can try plugging it in and test if it works. It is very quiet and blows nicely. Let it do its job cleaning your air at home. You can change the filter at least once a month or when the color looks dark already. You can create two or more so that you can place it in other rooms of your house.
In most buildings, air filters are already installed. It is one of the most important things to install in offices and big establishments.
