⭐️⭐️⭐️⭐️⭐️ Perfect Replacement Filters — These Filters Really Work!
⭐️⭐️⭐️⭐️⭐️ Perfect Replacement Filters — These Filters Really Work!I couldn’t be happier with this 2 Pack of 130i Replacement Filters for the PuroAir 130i. These filters are absolutely perfect! The moment I swapped them in, the difference in air quality was noticeable.They tackle everything:Food smells — gone within minutes.Human BO — completely eliminated.Pollen and dust — my allergies improved almost overnight.Smoke and lingering odors — wiped out quickly and consistently.Any household pollutants you don’t want in your air — these filters take care of it!The True HEPA performance is exactly as advertised, and the airflow on my purifier stayed strong with no added noise. They fit perfectly, seal well, and restore the purifier to like‑new performance.If you have a PuroAir 130i, these replacement filters are a must. Effective, affordable, and truly capable of removing whatever you don’t want floating around in your home’s air. Highly recommended!

Excellent design and functionality
Love this purifier! Picked up the 2-pack, one for each of two bedrooms. For its small size it really pumps the air through. Filter is thick and good quality. The control panel is really well designed with auto/lo/med/hi/sleep options and timer too. Runs smooth and quiet. I’m a clean air enthusiast and I highly recommend this.

Great Air Purifier for your home
We have two active large dogs who seem to keep the dust flying in the home. We needed something to help us control this so we purchased the PuroAir 240 and have found that it is great at reducing and almost eliminating our problem. The replacement filters are readily available on Amazon and it was priced reasonable for it’s size. The noise level is very low and it has multiple speeds to adjust for your comfort.

Small and Quiet
Very quiet. User friendly. No smells. It seems of good quality. Small and easy to place almost everywhere, Surprise such a small product can cover such a large area.

Easy setup and light enough for me to pick up without any issues. At 77 I have enough issues, LOL.
Bought at 5AM, delivered by 10AM.I opened the first one, read the simple instructions and setup the Puroair air purifier. That took almost 3 minutes after opening the box. Set it up in the living room after vaccuming the rug (got a lot of cat hair out). Plugged it in, it cycled through the setup as promised and then turned it on. Living room auto run, and green almost immediately (that vacum does a great job).Setup the second in the bedroom and after it cycled through its setup, I turned it on. I had not vaccumed the bedroom and the 240 immediately went to red. After a few minutes, it went to orange then green. I guess the air next to my bed is now OK to breath!Easy setup, seems like they are both running well, quiet when green (cannot hear them without standing over them), air flow is nice. Yes they have a plastic body but they are not high priced and I hope to have them running everyday.

Major Improvements in Air Quality
Was skeptical so did my research and these air purifiers came up as some of the best and highly rated. They are very quiet and really are unnoticeable only a slight white noise. My husband has one on his bedside stand. He has had severe allergies for years and both he and I noticed an amazing difference of the air quality within 48 hours. His nightly congestion and cough has improved tremendously and would go so far as to say the air purifier has helped more than any allergy medications! Had looked at less expensive models but will definitely say these are worth the money and am considering adding another one or two to encompass the main rooms.Our bedroom is a large room with tall ceilings. Our second unit is in the living room with tall ceilings and semi open area to a large dining room and kitchen. Both seem to be very beneficial even in large rooms. Wish we had purchased these years ago!Recent purchase and have been in use for less than a month. Have not reached the point of cleaning or filter replacement but can’t see how that would be an issue. We have not noticed an untoward smells or odors with initial use or operation.

The product is lightweight cheap plastic. The company ship to the UK yet the device requires a voltage step-down unit to cope with the 110V rated USA device. Company either dumb or dishonest. Factor in additional £50-100 for device to step down UK 240V. So far not seen source for replacement HEPA filters on Amazon either.

Bought it on amazon.es assuming that it would work here. Unfortunately it does not and have to send it back!I wish the seller had mentioned US plug 120v in the description
