will this get rid of cat odors

Asked by: peanut
It can, but you will need to purchase the Smoke Stop filter. The unit comes with a Particle filter in the unit, but that is the standard filter that only handles solid particles like dust, pollen, mold spores, and the like. The Smoke Stop filters have the same filtration, but they also have 2 - 4 pounds of activated carbon that absorbs gasses and odors. Thank you for your question. If you have any others feel free to visit or call us at 1-888-258-3247.

HEPASilent Air Purifier is rated 5.0 out of 5 by 20.
Rated 5 out of 5 by from Awesome product Got out stubborn cat urin smell. Neither a rental carpet cleaner and home unit that claims to out perform rentals could get out the smell. Also tried Urin Gone! As seen on TV. That did not work. The Blueair worked. My friends said if this can get out the smell of your 3 cats in your tiny apartment (700 sq ft), im going to tell everyone Blueair is the best. What can i say? This air purifier is awesome. Blueair is quiet. I have a different brand $150 tower for my bedroom where i wont let my cats go. It has a bluelight to kill 99.9% of viruses, etc. This machine is great but not as good. Its quiet but it says its filter never needs to be replaced and i dont advise that. The filter gets filthy even when the room is ocd clean without dust and everything in plastic.

Rated 5 out of 5 by from Now four years into having a Blueair 603. This is the best air purifier of them all we know! There is a big difference in the quality of the air we breath in our house! It allowed us to keep our old cat to which our daughter reacted before we got the purifier. Plus, very very quiet! I am just amazed at how very little noise this purifier makes. It really is only a whisper. We leave it running all the time at low or medium speed and are not at all bothered by the whisper. Love it so much, I am looking to buy one for my sister who lives in an apartment surrounded by heavy smokers. She`s bought other good brand purifiers without good results. I just don`t know yet which Blueair would be best for her, considering the heavy heavy cigarette smokes entering her apartment AT ALL TIMES! Perhaps it`s best if she tries ours and we see? Definitely ready to give her a beautiful gift for health if it makes her apartment air clean!

Rated 5 out of 5 by from I Sleep Better. Years ago I exhausted all available medication avenues--I take a mucous pill and two inhalers.  My Doctor said the last avenue to reduce allergic assaults on my immune system was mite-proof bed clothes which I now have, and an air filter.  After much research I found Blueair.  My fiance has a Great Dane and her daughter occasionally brings her cat home, so the Blueair filter helps me sleep better.

Rated 5 out of 5 by from Excellent product - well built We have had our Blue Air 601 for at least 5 years and anticipate that we will have it for the rest of our lifetime! We utilize the unit in our bed room having it come on a couple of hour before bedtime and an hour after we get up. It has made a tremendous improvement our sleep quality. The fan noise provides a wonderful white nose to eliminate any other outside interference noises as well. We are also members of the Blue Air Filter club and receive replacement filter every 6 months. I has been a pleasure dealing with the all the customer sales representatives over the years and would like to comment the company for retaining such high quality personnel

Rated 5 out of 5 by from Great Air Purifier!!! I bought this for my parents who live in California. My father had horrible allergies each Spring and even into the Summer and Fall seasons. Both parents have said their allergies are much better and his asthma is better as well. My mother also said that she does not need to sweep as often as there is not as much dust in the air. It's incredibly quiet on low and they leave it on 24/7. They loved this product so much that I am buying them a smaller one for their bedroom. I would highly recommend this product!!

Rated 5 out of 5 by from Quiet and Great Air Quality I received this unit as a baby gift, which was wonderful! That was 8 years ago, and the unit is still going strong and doing a wonderful job. How do I know? Each time I change the filters they have 'done their job'! And that is with our changing our house filters each month. If someone in our home is suffering from allergies, we take the unit into their room and they are much better by morning. I run the unit 24/7 and it does great! The unit is very quiet when on low ... so much so that at first I was checking that it was even on.

Rated 5 out of 5 by from breathe easy Allergy season was so bad this year that my husband went to the allergy doctor for the first time in his life. This air purifier was a big purchase, but worth every penny. (we got the biggest size for large space) We couldn't believe the difference! It relieved coughing, scratchy throat & eyes and cleared chest congestion. We now use it non-stop. It's wonderful to breathe easy again.

Rated 5 out of 5 by from This Really Cleans The Air We bought our Blueair 603 unit about four months ago after returning from an extended vacation.  During the three months we were gone my wife suffered terribly with her allergies.  We live in Florida, so we generally keep the air conditioner going most of the year.  After receiving the unit and setting it up, she finally got a full nights sleep ... after the first day.  Since then, we have both been sleeping well.  She also loves the fact that there is less dust in the house.  I would highly recommend this unit.
