An air purifier is basically just a fan + HEPA filter (and sometimes particle counter) right?

LOL... wear a face mask better la like this..

Dear Sifu's,

I would highly appreciate your 2 cents on the following air filter that I am surveying as it's within my budget. All your feedback is welcome...

went to a few shops to ask. mainly they are recommending sharp or panasonic.

any users of these brands here? can share your experience with it pls. hope to get one by today.

Did you know, if the fan speed (RPM) are not strong enough, those things traps on HEPA would end up release back out once you have turn off the fan.

so means the air purifier must be on 24/7 all year long?

I mean his cheap diy Hepa filter method. At least those budget type air purifier are good enough power to pull them traps inside the Hepa.

Thanks. Didn't of that.
But those are easy problems to solve. Stronger and bigger fans. Trap.
Anything else?

I am wondering because my Sharp is about 3 years old. I've used it very little, but it's a consumer grade device. And we all know about the models changing frequently, resulting in the needed HEPA fiilters no longer being available. If the current haze do not let up, the filter will soon get all clogged up, and I may have to hack and modify a filter that does not fit, to force it to go into an existing machine.

But really, I want 3 or 4 additional machines, and just can't afford to buy them all.

I thought every model/brand uses custom-made HEPA filter?


HEPA filter is the expensive component of an air purifier. No point buying an pricey filter and use it with a cheap fan.

Custom made filter? U mean as in different model canot fit different model? Yea thats right.
Im just wondering if got 3rd party company come out with compatible filter at lower price, assuming original manufacturer brand sure more expensive coz they can monopoly the market.

Anyone use Xiaomi Mi Air Purifier? Is it good?

It's much worse than that. Even the same brand, wouldn't always fit different models. For consumer level air purifiers, they like the change the model every few years. Nothing wrong with that, if they want their machines up-to-date so as to better compete against other brands, it's perfectly fine. The problem is that they then stop making the filters for the older models. After a while, you have a perfectly working machine, except that you need to change the filter, and can't buy it anywhere.

As for compatible third party manufacturers ... there's probably just too much variety in shapes. What with all those different models, and the constant change of models and shapes.

This isn't my personal experience. Just what I read on the www. Our own machine is still on the original filter. But we're probably well past the 50% mark by now.

Some of the better machines sell for RM2k. At that level, there's plenty left over to get a good powerful fan.

1st No-no: Air purifier with Ionizer & Ozone thingy are slowly damaging our body. Do not spend money on something which is harmful to us.

Check out a product and see whether got certified by third party or not. Anyone wants to filter haze, bacteria and viruses, only few premium air purifiers can help on this, one is below RM5k and another one is above RM10k. Work out on your budget. I believe they have installment package. Cheers!

P/s: I am using the one below RM5k and it really helps a lot during hazy condition now and years back. I recommended to my cousin brother few months back, their baby can sleep well now and both of the husband and wife got no more nose sensitivity & sinus. For us, is not expensive but worth it because every family member enjoying good air at home & it solved our problems.

Message me if you want to know more. I don't mind to let you try on my current unit.

They're big enough to clean an entire house? (500-1000 cubic meter).

what brand is the best , and how much it will cost ? plan to get one soon

Pls tell which one..

Would be great if you can share the name of the product here, after all forums are for the pleasure of sharing?

I'm using the one "Atmosphere" from Amway company, it able to do the job of CADR 250 cubic feet per mins. (aka 7.1 cubic meters per minutes).

Not sure which the best, every manufacturer always claimed theirs are the best. lol
See how much you spend on budget anyway and what purpose and how big your room..

I believe the fellow forum member share above below RM5k is the same one my dad using...
