Have a look at Venta. Available from Benova. LW-15 RM1999. Traps air particle on rotating drum and clean air emerges from the sides. Very quiet for LW-15 22 dB. 10W only. Only change water. Made in Germany or at least inspired by German Technology.

Only clean rotating drum with brush. No filter - the water is the filter.

Besides particulate size selectivity by using HEPA or any filtering medium, can also consider water as a filtering medium. There's Stadler Form's Viktor and Venta. Both are rotating disc immersed in water. Viktor at least comes equipped with a silver ion cube to prevent bacteria breeding in water. Also has the regular filters plus air fragrance dispenser.

How do you find it? Some say using it delay air con use but it can get warm after long.

Anyone experienced with stadler form? Viktor / Robert. Mind to share the maintenance cost and ect? Attract me with the beutiful stylish design, most importantly with the low energy consumption!

Robert is water drum filter air particulate purifier that users water as the particulate filtration media. Venta is the other equivalent competitor.

Maintenance cost is silver ion cube to sterilize water from becoming breeding pond for aerosol based pathogen. If air con is used and set very low, the water chamber needs refilling more often. Without aircond usage, the room humidity is raised slightly.

Additionally, you can use aromatic oil to "scentify" the room.

But these does nothing to remove or neutralize VOC, airborne pathogens. Anything that doesn't readily stay in the water won't. Cigarette smoke, pollen, brake soot, vehicle soot and haze particles somewhat or almost definitely. Use it on combination with AC that has air purifying function like nano-e, plasmacluster, negative ions and photo catalytic ( TiO2) filters or Corvan air purifying lamps or plants that purifies those other stuff.

If living right in heavy vehicular traffic zones, they do not affect NO2 as with most residential air purifiers. For that a very large surface area photocatalytic purifying filter is required or spider plants that helps reduce their concentration. See here for beneficial plants.

Cant find this model from lazada...
My room dust accumulate faster than before after house renovation, wonder if it is because the air flow inside house change.
Dust on fan blade can be easily noticed 2 weeks after cleaning...

Dust not isolated to room but where it's brought too even outside. And as you observed the wind can bring it in unless the contractors keep them in a waste bag. Even that will still have residual dust. Water based vacuum or water drum air cleaner will trap these in water. For reno, best to get cleaners to do pre-move in cleaning after the tong roro have been removed.

Yes filter replacement cost is an issue - hence why i steer people away from branded & expensive brands like Blueair & IQAir unless they are loaded. Xiaomi replacement filter costs around RM 60-80 so it's actually very affordable changing it every 6 or 12 months.

Venta is not without its benefits. It's quite similar to those water filter based vacuum cleaners where they use water to trap dust.

It's good for those dusts that can be seen (PM10 above), but it still can't replace an air purifier since PM2.5 is the one that is more harmful to us as it can go into our lungs.

Humidity is best kept at 40%-50% to prevent mold & bacteria. In my experience, for my bedroom at least, even with aircon it's barely reaching 50% so actually no issue with air being too dry in air conditioned room.

When air is moist enough to the extent it won't be able to pick up water anymore, it means 100% relative humidity = condensation, that's super bad news. Though i doubt it is able to drive the humidity up to that point. But my point is, it's best to keep humidity in the range of 40-50%.

Also, i am curious though, don't you need to top up the water in Venta? I remember my Sharp 2-in-1 air purifier with humidifier consumes 100% of the water in its container in 1 single night, making me lazy to use the function after a while.

Plus, i don't quite get it. Venta sucks in air with dusts into the water, and then evaporates the water full of germs, doesn't this mean that it's reintroducing germs into the air?

Based on the above premise, if you don't clean it often (like every 3 days at the minimum which nobody would bother to), those accumulated germs in the machine are going to cause all sorts of respiratory problems after having been misted into the air by the machine.

If not mistaken Venta and other water based air filtration has a replaceable Ag ion module to disinfect the water.

The additive is mainly to reduce water hardness, as malaysia do not have hard water issue, not really neccessary to add.

My bad, I was thinking of Stadlerform's Robert which has the silver ion module to keep the water bacteriostatic.

Seems like the newer models from Venta are touting 0.3 to 0.07 micron particulate matter removal.
