I’ve been using the APH3000 Air Purifier for a couple of days, and I’m really impressed with how well it performs. My bedroom is fairly large, and this unit has no problem keeping the air fresh and clean. The built-in air quality monitor is a nice touch, I can actually see when the air improves after it kicks on. The fan speed is really good. The washable filters are a big plus for me. The purifier is surprisingly quiet even in Turbo mode, and Sleep mode is almost silent. Read more

This air purifier lives up to the "small but mighty" description. Its compact size doesn't diminish its ability to noticeably improve air quality. Setup is straightforward. Within minutes of unboxing, the purifier can be plugged in and running, effectively purifying air in it space. A key feature is its quiet operation. Even at the highest setting, the noise level is comparable to a soft hum, making it suitable for bedrooms or home offices where quiet is important. There is no disruptive noise - just clean air circulating. The automatic air quality detection is a notable feature. The purifier monitors and adjusts fan speed based on air quality, ensuring optimal purification. The air quality indicator changes colors to reflect air quality, indicating the device is working effectively. The indicator returning to a "good" reading after cooking or when pet dander is present is a positive.. Overall, this air purifier fulfills its promises. Its size makes it versatile, fitting on a shelf or nightstand. It's powerful for its size, improving air freshness, reducing allergens, and minimizing odors. If you need a quiet, easy-to-use air purifier that performs well, this model is a good choice! Read more

Bought two of these and they work fantastic for our 1800 sqft home!! The replacement filters and easy. You can barely hear it running, and we’ve noticed a huge improvement in quality of air. Read more

Ownership time: 2 Days First I should mention that the reviews are not to be trusted, especially the ones who go, "Oh wow, I noticed a change immediately." This product is not magic, not by a long margin. This is a passive sanitizing air fan. The only 'gimmick' it has is that it pulls in air from the environment and forces it through a multi-stage filter. For some environments, it will do what it says. It works, it works well enough that I can notice a difference, but I am very observant of my environment, to a level most wouldn't really think of. I suppose if you are actively searching for a contaminant filtering air fan, this would mean you are just as observant. Does it cover the area it says it does? No, it covers an area much smaller than mentioned, especially if that space is not in the same room. Setting up the fan, you need to understand how the air moves through the space you are attempting to clean up. I purchased two of them, one for my bedroom which has a small air leak from the very old windows, and then another one in my hallway outside of my bathroom which the air will travel towards from my bedroom. I have them running continuously on the lowest setting, and it is doing what it says, however if you are going to count of using Auto mode, I would find another product that is more of an active sanitizer than this product. It also is not something that works within the first few hours, it will take days for it to exchange enough air with the environment to sufficiently clean it. This leads me to my next issue with it, the 'air quality' gauge it has. I don't feel like it is something you can trust, I trust it is analyzing the air being pulled through it, but it is a terrible gauge of the air in its totality. So what is this product good for? Is it compact? Yes-ish. Is it quiet? Yes, unless the belt that moves the fan is just loose enough to create noise. One of the two I ordered definitely has this manufacturing defect, its not bad enough for me to need to return the product. Is it sanitizing the air? Yes, but only if I have the fan running continuously for several days, I wouldnt trust auto mode to do the job. Is it clearing up smells? Yes, definitely, but this is again only because I have it running continuously and not on automatic. Is it easy to set up? Yes, just remove the tape, remove the bags, plug it in, and its off to the races. Did I need to read the manual? No, but it helped me understand the product well enough to make choices in my settings. Where could it have been improved? If it had an active sanitation function, or the Auto mode was a bit more trustworthy I would give this a better grade. Was it worth the $78 I spent for each? Yes, any cheaper it would be well worth it. Read more

Small but powerful. Live in a one floor three bedroom apartment and drastically reduced amount of dust settling throughout the home. Has a scent feature that works spectacularly. Use same oils for diffuser and lasted for theee days with minimal oil. Filter easy to clean and has nice auto features that showcase a turbo mode to help filter during cleaning events. Recommend as value for unit is high! Read more
