    It is exactly as advertised. Cant say much about effectiveness as dont have air quality checker, but the filter started turning black within 2 days. Thats enough to say it works.

    A drummed-down air purifier that does just what it needs to do – purify air. The one year kit is the best package, in my opinion. Best to go for 1 one year kit and then additional DYI Air Purifiers if required.

    Works well.. noticable difference in the air quaity as am able to breathe better with substantial difference in stable sleep ..am ordering two other for the other rooms

    Two suggestions :

    1) the velcro strips provided should be two for holding the filter tight to the fan and also prevent the filter from falling/slipping off
    2) add some weight to the base of the fan so that the unit is more stable, If i put the fan at an angle the unit becomes unstable

    Also have a Question : Is the pre filter washable ?

    • (verified owner):

      Hi Gaurav,
      The pre-filters are not washable.

    As of now looks good…Can feel the slight difference in the air quality.
    Not sure how much effective it is but some effect I can notice for sure.

    (verified owner):

    This is a very cost effective and simple setup. Filter replacement ( HEPA ) which needs to be done regularly in our current poor air conditions is also pretty cheap.
    The main drawback that i experience with this setup as against other brands is that it tries to push air and most of the air is reflected back. So the amount of air passing through the filter is much less. Traditional air purifiers use a suction to pull air rather than push air and cleans a much larger volume of air compared to this model.
    I hope that with the improved model that is being introduced – Canon, this problem will be much reduced.

    I am in Navi Mumbai and area is not that much polluted. Since I suspected some dust allergy problems and the result in EṣR count,I bought the Original DIY Air purifier 2 months and it is working very well. Dust I have seen earlier gets accumulated.HEPA is not turning black so far. Still I feel it is worth for the cost that I bought (Less than Rs.4000 – at my doors). I do not cough if the fan is stitched on now.

    I strongly suggest to all those who have respiratory problems, even if they live reasonably non-polluted area.

    This product is very good under the prescribed conditions. The evidence of its effectiveness is clear when you replace the used filter. Every particulate trapped by this used filter is likely one less particulate in your lungs. And trust me, it literally turns from white to black at the end of 2 months.
