PuroAir 400 HEPA Air Purifier

The PuroAir 400 HEPA Air Purifier is made for larger rooms and open living spaces where a small desktop purifier is not going to cut it. It uses a 3-layer filtration system with a pre-filter, HEPA filter, and activated carbon filter to help reduce dust, pollen, pet dander, smoke, odors, and other common indoor air particles. PuroAir lists the 400 as covering rooms up to 2,000 square feet in an hour, with auto mode, an air quality sensor, filter replacement alerts, quiet operation, and a 14.7-pound design that is still light enough to move from room to room.

Why Rob Recommends It:
I recommend the PuroAir 400 because indoor air quality is one of those things people ignore until allergies, pets, dust, smoke, or stale indoor air make it impossible to ignore. This is a better pick than a tiny budget purifier if you want something for a living room, bedroom, home office, open floor plan, or larger shared space. I also like that it has auto mode, so it can adjust fan speed based on the air quality instead of forcing you to constantly mess with settings.

Rob’s Pick:
Choose the PuroAir 400 HEPA Air Purifier — 1 Pack with the filter subscription. The 1-pack is the right place to start unless you already know you need multiple units. I would add the filter subscription because PuroAir recommends replacing the filter about every 90 days, and the subscription includes filter savings, auto-delivery, and lifetime purifier warranty coverage while the subscription is active.
