The inclusion of a toll-free number and support email address in the manual is also a thoughtful touch.
I am particularly impressed with the whisper-quiet operation of the Low fan setting. Even the Medium fan setting is relatively quiet, which is a definite plus for me. However, on the High fan setting, the noise level does increase significantly. This may not be ideal for individuals seeking a completely silent environment, but for those who enjoy white noise to drown out external disturbances, such as barking dogs or garbage trucks, it is perfect. It is worth mentioning that I have encountered air purifiers and humidifiers that produce louder noise levels than this model.
The air purifier is designed in such a way that unfiltered air enters from the front, while filtered air exits from the top. The user manual advises keeping a 1" clearance from any wall or furniture, which is a practical recommendation for optimal performance. The manual also emphasizes the importance of switching off and unplugging the unit when not in use. This is likely due to the UV and negative ION functions, although it may be inconvenient for some users to unplug it every time they turn it off. A possible solution could be to utilize a power strip.
Furthermore, the purifier features a SLEEP mode, although the user manual does not provide detailed information on how it alters the functionality of the device. It does, however, mention that SLEEP mode turns off the LED lights. It is worth noting that unlike other brands of air purifiers, SLEEP mode does not adjust the fan speed. In order to provide a comprehensive user experience, it would be beneficial if the user manual included clear instructions on the specific changes that occur during SLEEP mode.
The InvisiClean replacement HEPA filters, which are model IC-1312, are readily available on Amazon or through InvisiClean. It is recommended to replace the HEPA filter every 6-12 months and clean the prefilter monthly using a vacuum cleaner. The manual also provides the model number for prefilter replacement, should it be required.
Having previously owned an InvisiClean air purifier for our master bedroom, we decided to purchase another one from the same brand when converting our junk room into a guest bedroom. We opted for the smaller unit due to its size, and we are pleased to report that it performs just as effectively as our previous model. The only minor drawback is the noise level on the higher setting, which is relatively loud. While this may be an inherent characteristic of the manufacturing process, the low setting offers an acceptable noise level.

However, if you are sensitive to noise, I would recommend placing the purifier at a distance from your bed. Overall, I couldn't be happier with this air purifier.
I also purchased two other Levoit air purifiers, the Core 300 and the LV-H126. The Core 300 is also great, but I read a review stating that the LV-H126 emits extremely high levels of EMF radiation. While some may argue that it's not an issue, I believe it's better to avoid unnecessary radiation in the air. Using an EMF detector, I found that all air purifiers emit a certain amount of EMF radiation. The Core 300 had acceptable levels, but the LV-H126 was off the charts.
This led me to search for effective air purifiers without the added radiation concerns, and the InvisiClean air purifier fits the bill. Although it is quite large, it is highly effective compared to my other three purifiers, and it emits only a fraction of the radiation even my smallest desktop purifiers do. The replacement filters for this purifier may be a bit pricey, but it's a trade-off I'm willing to make. It's better to invest in a quality purifier than to be exposed to high levels of radiation or have ineffective filtration.

I did encounter a minor issue with the smell when running two units simultaneously, but I was able to resolve it by purchasing two timers and offsetting them by 30 minutes. While one unit should be sufficient for most setups, I needed two due to the configuration of my airhandler. I reached out to the company for assistance and they were extremely helpful, offering a full refund if I wasn't completely satisfied.
Even though I experienced a problem with the unit not functioning after replacing the bulbs, I was pleasantly surprised by the exceptional customer service provided by Odorstop. I contacted them and Jessica from customer service promptly responded, instructing me to send in the unit for warranty repair. Within 10 days, the repaired unit was back in my furnace, working as intended. This level of customer service exceeded my expectations and reaffirmed my belief in the quality of Odorstop products.
I also want to mention that the mounting method of the bulbs may not be ideal, as noted in a one-star review I came across. However, I found a workaround by rotating the unit so that all four bulbs hang at an angle. This provides better support for the bulbs and reduces drooping and stress on the bulb sockets. I have attached images to illustrate this mounting method.
