Review on 🌬️ Enerzen by OION Technologies LB-555: Powerful 6-in-1 HEPA Air Purifier for 4000 Sq. Ft. - Clean Air Purification System by Angie Zhang

It is not clear why the product name contains a HEPA filter when it does not contain a HEPA filter. It has the following 6 elements: 1) antibacterial pre-filter 2) carbon filter 3) UV lamp (to kill bacteria/germs) (there are 2 in the LB-555 model) 4) photocatalytic PCO 5) ozone power up to 650 kV . ft6) Negative ion generator (negative ions bind to dust/allergens and fall to the ground) up to 4000m². ft. If you use it for this purpose only, it will cover 650 sq ft. ft. NOT 4 thousand square feet. ft. On an area of 4 thousand square meters. Feet is only used to generate negative ions, which emit negative ions that combine with dust and allergens, causing them to fall to the ground, preventing them from being inhaled. Also, it's not clear why coverage areas are listed in square feet rather than cubic feet. It really needs to be in cubic feet to get a more accurate idea of coverage. This seems like sloppy labeling, but hopefully it's not misleading as I think people can understand that 4000 sq ft with 8 ft ceilings is very different from a warehouse or barn structure with 20 ft ceilings. You really need to look at how many times an air purifier can completely transform the air in a room, and it's always measured in cubic feet. Aside from some dubious claims suggesting it's a HEPA filtration system and the ambiguous 4K square figure. ft indicator is easy to use. There are two options on the machine: negative ion generator or ozone cleaning. I like that it's easy to use, but I'd caution anyone with kids in the house not to leave it where they can access it. The ozone setting is used ONLY when the house is empty, including plants. I'm just planning to use it as an ozone generator when needed to eliminate smoke odors and it's a great tool for that.
