DIY Homemade Fan Filter Machine using  USD 6 in 5 Minutes

The above figure shows the state of the filter after six 6 days of use compared to the new unused filter.  Imagine all these dust in your lungs.

Filter To Be Used In An Enclosed Air Conditioned Room

I have done some research.
There is a 3M Filtrete Four pieces of 19cm x 30cm: At RM53 or about USD12;  can be fitted to a table fan.  Two pieces are  needed at RM28 OR USD 6.   3M Filtrete filters come in various sizes.

For reviews on the 3M Filtrete, visit:


This idea is very similar to this NUS idea that was featured in the Star in 2014.

Try it.

Cut the filtrate into the size to be fit into the fan metal casing.

Cut the Filtrate filter into in a RECTANGULAR shape   to be fitted into the fan’s metal casing.  The white colour stripes are the double-sided tapes.  The  filter appearing on top on the left  is the one  after 7 days’ used.



Insert the filtrate into fan metal casing

Insert the Filtrate into fan’s metal casing secure it with the double-side tapes.

After re-attach the metal casing with the filtrate.

Re-attached the metal casing with the Filtrate inside.  There should be  ‘over-lapping’ parts at the edge of the metal casing as indicated to help you fasten the filter properly.


This is how the filtrate look like after 3 days

This is how the filter  look like after 3 days’ of use.  Notice the parts by the side and in the middle are of lighter colour.



The result (on top)  after 7 days as compared to the fresh one below.  The Filtrete filter on the right, I bought them from HomePro while I was in Bangkok.

Note: I will not recommend to fit it to the air conditioners.  It did not work too well for mine.
