Hi guys, do provide me with some guidance/opinions on selecting between these 2 air purifiers : DYSON Cool Formaldehyde TP09 or AMWAY Lombok III AP-1520C

Will be moving into a newly renovated home (new paints, new built in cabinets, furnitures etc) hence is looking to invest in an air purifier which is efficient in eliminating VOC’s and formaldehyde.

Seems like the new Dyson TP09 air purifier has got some really good reviews.
Any users of the AMWAY air purifier here that’s able to give some input on the efficacy?

What is the cost for each replacement filters ?

It'll be cheaper to exhaust the air out (change the air). I'm afraid that (due to the size of the unit) it may clog up the filter wastefully.

DYSON - RM299 for replacement filter
Not sure about the COWAY one as what I enquired is for a 5year rental contract, fee is RM90/mth including service every 2months plus filter change as required (fine dust filter change every 4mths, HEPA 1year, catalyst+deodorisation every 2yrs)

Which unit are you referring to? DYSON or COWAY

just air the house
but frankly, the formaldehyde lingers for years.
it's better to use safe material.

Dyson’s are junk. Airflow is crap, noisy, and the after sales support is nonexistent.

My personal experience and opinion.

A kitchen cabinet maker told me E2 is the norm in Malaysia and questioned me if anyone fell sick due to long term exposure to formadelhyde in Malaysia.

Most air quality / formadelhyde sensors have a limited lifespan. I was told Dyson’s one would last lifetime. The noise doesn’t bother me much in fact my wife prefers to have white noise at night.

that's the reason I choose ikea.
formaldehyde free

I have a cheapo wardrobe. 5 years of airing still stinks of formaldehyde


BTW, consider xiaomi air purifier. they have dedicated filter for formaldehyde

Dyson's purifiers are extremely overpriced...

Yea it’ll be a continuous emission unfortunately. Hence is looking to invest in a reliable air purifier that is able to effectively reduce formaldehyde levels

You’re using a dyson then I’m assuming? How’s the experience thus far? Worth the money spent?

I’ve bought one for a smaller bedroom actually. Is looking for other reliable options for bigger space - living room with open kitchen (heaps of new built-in cabinets there)

basically the air filters use charcoal activated carbon to absorb the formaldehyde.

so choose a filter that you can afford to change frequently.

the center core is the carbon filter


Dyson use catalytic converter to remove formaldehyde
Cryptomelane or kalium manganese oxide
Dyson claims it works but I am skeptical of it. the converter looks like easy to get clogged

I’m happy with it. At least I have a peace of mind the air quality is good for my baby. The app is sleek and easily integrate-able into homeassistant. It can be noisy at max speed but it’s still tolerable for me. In fact its overall air quality reading is consistent with xiaomi one that I have in the living room. What I can’t verify is the formadelhyde sensor as my room doesn’t have the smell from furniture to begin with.

By the way, I bought a custom filter filled with activated carbon for the xiaomi air purifier in living room.

Yeah Xiaomi is the best bang for buck, and filter price is cheap while can be monitored and automated using the app.

Coway is a lot more expensive in the long run.

so many dupe acc promoting coway in multiple thread. nice try tho.

I'm in similar situation now, going to start airing my house after I have installed the safety grills on. May I know eventually which air purifier did you go with?
