HEPA filter is not a high tech device, it’s a mass produced commodity, like coffee.

Sure, quality varies, but they should all function well enough for domestic function of capturing dust and pollen.

I say this as someone who has terrible allergy, I know when they work and when they don’t, no lab equipment necessary.

The the main thing that matters in air purifier is size, for delivering volume of cleaned air.

The problem is we keep putting them into strange shapes like cylinders and every purifier has an incompatible cartridge. And also we made a filter and a fan into a strange luxury product that costs hundreds of dollars.

I will be switching to IKEA purifiers because they are flat, simple, and filters are cheap.

I have a Coway Airmega 150, and have been very happy with it. Coway makes a variety of models and they all are well designed. Mine is on the smaller side but it is quiet, automatic, and no annoying screens or beeps.

Those IKEA purifiers are garbage in my opinion. I sent all of them back. The flat one shook all the time and was loud, as if the fan had been badly balanced or not balanced at all. I was also not convinced by the built quality compared to my Xiaomi Air purifiers.
