RENPHO Air Purifier for Home Large Room Up to 356 Ft², True HEPA Air Cleaner Filter for Allergies and Pets, Intercept Dust Pollen Smoke, Quiet 28dB

Seriously, my husband can be in the room and poot next to it, and it will detect it 😄 and starts glowing orange lights or red lights, working harder to clean the air! This one has the best filtering capability, with so many layers...actual charcoal screen, hepa filter, carbon filter, mesh screen, etc. The way it detects something in the air is sooo crazy to see! The different color glowing lights let you know how strong the odor is and how hard it's working to clean it. Not just odors either, stirring up some dust while cleaning, dog or cat fur gets near it..it detects it and works away. This is when it is on auto-mode. Perfect for my dogs and when I'm burning dinners, or smoke or odors come in from outside. Replacement filters are not expensive and last a long time for me. You can find them made by other manufacturers that work just as well as brand name. I'd say the filters last about 6 mos dependent on how much is being cleaned in the air, of course. You can clean the screen and filters by hand, if you can't afford a full replacement set. I did this a few times. When you do this, remember to hold down the red lights on the end to reset them as if it were a new filter replaced. The generic filters are about $25 now compared to the brand name that are now (ahem) $75, and I can see in my purchase history that I have replaced the entire filtering twice since 2019, once in 2020 for $26, so went through 3 filters, since Nov. 2019!!! It is a sturdy machine and not heavy, it won't topple over easily, and has a nice rounded rectangular design (not boxy). I had a smaller Levoit cylinder-shaped filter before this one, and the Levoit kept falling over and getting knocked off the table, because it was too light. I'm pretty sure it broke, since I went to buy this Renpho. I like that the top of this one is shaped so that it's easy to grab it and move to another room, if wanted. It's a soft quiet air sound when in blue lightest cleaning mode, but even at the highest red cleaning mode, it's still fairly quiet. The lighting can be turned off, but the blue light is pleasant at night, so I leave it on. I used to run this 24/7 non-stop on auto-mode...no problems for 4 years!! I just started trying to cut back on utilities usage, so I now make use of its timer feature! Highly recommend this model air purifier. Get it if it's still around!!

I LOOOOOVE this product!! It’s soo easy to use and powerful for its size! I’ve had air purifiers that had similar sqft stats that were insanely bulky and an eyesore. This is the perfect size—not too big, but also not too small, juuust right.Also, in the past the filters and cage door were a pain in the rear to install and fasten. This is super simple, even though there’s multiple filters. I didn’t have any trouble installing them and attaching the backing back on. The lighting is very soft and not bothersome, which I appreciate. You can also turn the lights off if needed. My kids really love it because it looks like it has little kitty ears, haha.It’s not too noisy either. I almost was hoping it would be a little louder because it also serves as our white noise maker while sleeping. It’s not really a complaint I think most will have though, haha. This thing really packs a punch. When the sun comes through the windows, I don’t see a bunch of little dust specs floating everywhere, which makes me feel SOO much better knowing it’s giving us fresher air to breath (especially considering we are in WA state where we are quarantined in our homes due to COVID19, blah)Over all, I’m just super impressed with this product. I would most definitely recommend it! In fact, I already have shared it with a Close friend!!I will note however that it didn’t come with a remote control, which was one of the star ratings I was asked. I’m not sure if it was supposed to or not, but regardless, I’m happy with my new air purifier ☺️

I initially bought one RP-AP001 and one AP068 due to fires in the state with the idea that the AP068 would go into a smaller room. The AP068 was noisy, and my unit simply wasn't effective in filtration at all. I sent it back and bought a second RP-AP001.The pictures in the review are from unit no. 2 purchased a week later. Both appear to function identically. I also measured noise and power consumption with it set to manual low, medium and high. If you set the unit on auto, it changes speed based on particulate matter sensed by the unit. Turning off AQ turns off this function and it stays in the selected mode so the noise and power consumption is the same between the modes.Using a calibrated sound meter held about 45 degrees away from the front of the unit approximately 2.5 feet above and 2.5 feet forward of the unit, you can see it's 36.9 dBA on low, 46.7 dBA on medium and 54.3 dBA on high. High is definitely very noticeable but I will say it's probably not worse than the smaller AP068 on its higher settings. It makes sense. The tiny unit has smaller blades that probably have to spin at a higher RPM to be effective.Where the RP-AP001 shines is on its low and medium settings. Medium is fine during the day you hardly notice it. Set it to low (which is also the mode activated if you press the sleep button) and you'll be hard pressed to even hear it at night when you sleep. And the 37 dBA is measured pretty close to the unit. I suspect this is why people complain that it isn't working--it's extremely quiet on low.I also threw the RP-AP001 on a watt meter and you can see it's: 27 watts on low, 37 watts on medium and 49 watts on high. At 27 watts, that's less than a TV, computer and about the equal to two spiral fluorescent light bulbs.I didn't bother to measure the AP068 at all because the noise level, even on its lowest setting, was just too loud. And it really didn't pass the one thing that mattered the most: particulate matter.To see how well the RP-AP001 filters air, I put a VSON air quality meter near the outlet with the RP-AP001 set to low and saw particle counts fall to zero for both PM2.5 and PM10. I had recently replaced the Plantower PMS3003 sensor in the VSON unit as the original failed after three years of use. Similar Plantower sensors are used in Purple Air's IOT air quality sensors and after observing raw realtime PM2.5 counts from three Purple Air sensors that ring our neighborhood, i'm confident it tracks fairly close to at least what Purple Air's units report.Overall, so far I'm very happy with the RP-AP001's. Filter replacements look to be reasonable but we'll see how the units hold up in the long haul. For now though, at the $100 or so the units cost, they do appear to work quite well in what they're meant to do: filter air.
