I tried the cheap IKEA model and with my severe dust mite allergies the model was insufficient in comparison to calm my sixth sinus-bound sense.

My main suspicion: In my last 3 abodes with pre-1955 construction in East Coast, the pre-filter on the top Wirecutter pick needs to be cleaned 3x per carbon filter replacement in order to reduce largest particle accumulation on the carbon or HEPA filters.

The inexpensive IKEA model did not have a viable and easily cleaned pre filter as far as I could figure out.

The ikea Fornuftig has a snap-on piece of cloth covered plastic that serves as a pre-filter, a replaceable particle filter, and a replaceable optional gas filter.

I've found that taking a shop vac and leaf blower to the pre-filter works quite well to get it clean.

That said, the Ikea air purifiers only make sense if you have a room that's about the right size for the Fornuftig. Their larger purifier is worse value, and you're better off looking at something like the Squair.

Just buy three for the same price as one expensive model :D

I have mine hooked up to smart outlets and particulate meter to automate them. I just wish I could control the speed.
