This was bought as a gift for my Mother-In-Law. She struggles a lot with her allergies and congestion, especially in the winter. She has two big dogs who shed a ton and are constantly in the bed with her. My MIL also lives in an older home. She's found that she tends to have a hard time breathing at home and is constantly coughing all winter. This air purifier was exactly what we were looking for. Since using it, she has reported being able to breathe so much easier. She said the air even “feels cleaner.” The instructions are super simple to follow on the air purifier and she loves the fact that it's incredibly quiet while running, so it doesn't disrupt her sleeping.

I am very impressed with this air purifier. It makes a noticeable difference in air quality within just a few hours of use. The unit runs quietly even on higher settings, which is perfect for running at night. With multiple pets in the house, I've seen a big reduction in pet hair, dust, and odors. The filter is easy to remove and clean, and the coverage area is great for larger rooms. Definitely worth the purchase for anyone dealing with allergies or pet dander.

This air purifier is excellent! I have a few dogs and it literally eliminates any odors from them within minutes. Also helps with cooking smells and stuff which is great! Also it's really compact and fits in a bunch of different areas because it's not bulky or anything. For the price you definitely can't go wrong with this KNKA air purifier, I highly recommend. It's also really quiet which is another big plus.

Been having a problem with dust in my house for a while. A friend recommended getting a air purifier a while ago. Was back and forth about it, but I finally decided to give it a shot. What can I say! It actually helps! Not as itchy and my cough which I was having, actually sounds not as intense. Dust is a really issue and I never realized that cleaning room everyday doesn't really help that much since it's also in the air. Don't get me wrong, you still need to clean the room, but having a air purifier as well makes a huge difference. Well worth the money!!

I really fell in love with these things. I have four in my home and ask whoever a lot cleaner before I purchase them. you can whack them. run if you don't pay him any attention unless you want to. but when it comes down to clean up got so many of them off and and sit there and say a cuss word how dirty it is Filter. as far as to explained, I'm sitting there thinking like God I'm breathing all that. I'll back them that filter off and tap it on or something cuz like didn't come on for it to be changed. it's just out there you in my house and I cleaned it. put it back together or numbers went down there and so I do that to all. the somewhere got more than others. I have two a smaller. they work great Carol

Have not had any problems except for sometimes it will randomly jump up to 999 even after I clean it, resolves eventually after leaving unplugged for a little while. Can't figure out how to get it to put out a fragrance though. The air that comes out of it smells so clean so it definitely does what it is supposed to.

Very quiet and efficient purifier. It detects the slightest change of air quality and quickly gets air back to normal. Very easy to set up and get started. I love the auto feature. With so many home air purifiers to choose from I highly recommend this KNKA air purifier.

This is the perfect size for my room is not too noise is easy to operate I can adjust in the way I want speeds Light, and time .the only thing can improve is the way too control the oil for smells but the machine is really good and not too bad I absolutely recommend it

When I received and unboxed the KNKA PRO air purifier, I was surprised at how small the unit was. It is about the size of a small preschool backpack. The machine looks visually pleasing with attractive lights and a professional modern display. The HEPA filter seems to be high quality and is easy to exchange. Unfortunately, I do not see the value in purifying the air with this product. We have a litter of puppies in one room along with their mother and accidents happen frequently. I purchased this machine to help remove the smell from the dogs. However, it does not seem to remove these odors at all. If I put the purifier on automation, it rarely comes on except when we start cooking. Then it reacts to moderate to poor air particles. Other than that, it does not activate at all which I find very strange. The essential oils compartment is also disappointing. I expected it to be inside the unit where the air passes through to distribute the fragrance. Instead, it is just a small shelf inside with some holes. It does not diffuse essential oils nearly as well as a regular diffuser. Overall, I am very unhappy with this purchase and consider it a waste of money. Sadly, I cannot return it because I no longer have the original box. This machine did not meet my expectations for air purification or odor removal especially in a home with pets.

This unit (APH3000) is not as described. WRONG unit was and IS still being being advertised incorrectly. This unit cleans up to 2325 square feet! I purchased stating this unit was 3200-3500 square feet, which is the APH4000. I see listing changed today (11-12-25), however it is STILL ,listed incorrectly. BEWARE of purchasing without researching machines. FALSE advertising.
