No such thing as no need to change filter for any AP. Only pre-filter are washable at best. You can continue to use the filter until turn black, but don't expect it to function as well as a well maintained filter.
U need to understand why is there a need to change filter first.
The reason is due to efficiency level of the filter will drop as the usage is alot
Sorry i meant to say, would you be able to recommend an AP that doesn't require frequent change of filter and/or can wash filters instead of having to buy new ones?
Also considering Phillips AC1715. Thinking of buying during the 11.11 sale. Anyone here have a review?
