Blueair makes solid, quiet purifiers — but like most sealed-unit brands, the sticker price is only the start: proprietary filters add up year after year. A high-airflow MERV-13 kit matches or beats the clean-air delivery and uses standard filters you can buy anywhere.

With sealed units, you're locked into the manufacturer's filter supply for the life of the machine. With a MERV-13 kit, filters are a commodity: 3M Filtrete from ~£58 a pair, no lock-in. Over five years that difference dwarfs the upfront saving.
Frequently asked questions
Is a MERV-13 kit as quiet as a Blueair?
At comparable airflow, yes — the Luggables kits run under 40 dB. And you can run a bigger kit on a low setting for the same noise but more clean air.
Can I use non-proprietary filters?
That's the point — MERV-13 media is a standard replaceable part, so you're never tied to one supplier.
