Customer Reviews
Good quality, delivery took a bit
I ordered the Series 400 Air Purifier a few weeks ago, along with a couple of extra pre-filters. The ordering process on the website was straightforward enough, no real issues there. Shipping took about 8 days to get to me in Oregon, which felt a little long for an air purifier, but it arrived well-packaged and undamaged. The unit itself is solid, definitely all-metal like they advertise, which is a big plus for my sensitivities. Setting it up was easy, just plug it in. I noticed a difference in air quality pretty quickly, especially with pet dander. I had a question about filter replacement intervals so I emailed customer service; they got back to me the next day with a clear answer. Overall, happy with the product's performance and the support, just wish delivery was a touch faster.
Decent price for the bundle
I needed new filters for my 160R2 and was looking for the best deal. I signed up for the newsletter and checked their site for sales. Ended up getting a filter replacement bundle during a seasonal sale, which saved me about 10% compared to buying everything separately. It wasn't a huge discount, but every bit helps. The value was definitely there for getting genuine HEPA and activated carbon filters. The purchase felt worth it.
Good filters, fast shipping
I bought replacement HEPA filters. They fit perfectly. Shipping was quick, got them in 4 days. Not much else to say, they work as expected. I'll buy again.

Share tips, ask questions & help fellow shoppers save more
Thinking of getting the 160R2. How long does shipping usually take, like if I order it to California?
Do they ever do sales on the air purifiers themselves, or is it mostly just on filters?
