When this arrived, I was a bit surprised because it is bigger than I thought. In the picture it, and thinking it only covers 100 sq. feet, I was thinking it was like one of those ionizers you plug into the wall and is the size of a lightbulb. But it is much bigger than that, and performs much better than I ever thought a smaller unit could. (You'll have to remove the plastic wrap from around the filters, or else it'll choke and overheat trying to move air through plastic, which is impossible....also, removing the cover is a bit stiff the first one or two times, then it gets easier....you'll see what I mean) I have many HEPA air purifiers around my house, I was a World Trade Center first responder and have respiratory issues from that. Plus I have two long haired dogs to add to the mix. They bring hair, dust, dander, and dog smell. So many units cost a small fortune to replace filters, some the filters are as expensive as the unit. I looked it up and these are not that way. I can buy plenty of filters to replace as needed without draining the bank. But, it also seems to perform very well. How do I know? Read on.... I use two different air monitoring units/systems to see how "clean" the air is. I noticed the numbers improve when this was used in a certain room. In this case, I used my kitchen as a test area. Tonight I made hamburgers, which of course fried in the air fryer, releases lots of indoor pollution. You can smell it and it can last awhile. With this in place, on high, the smell was mostly gone in an hour. Without it, you'd still be smelling the fried burger smell in the kitchen, the next day. The air quality monitors confirmed this as well. So, in summary, I'd buy more of these and less of the larger units that have outrageously priced filters. Putting these in a 10x10 room is very doable and for the price of the unit, and the filters, I feel is a better way to go. The unit has a timer system that can be used to shut off after different hour intervals, it has an adjustable blue accent light (not a UV light), and 3 fan speeds. Nothing more would be needed on a unit like this. Basic, but cool with the blue light, or not if it is annoying you can extinguish the light. Time will tell how well the unit holds up and how long the filters last, but I'll say I was impressed with the motor inside that powers the fan blade. And the unit is heavy for its size, no lightweight. That to me means it has a heavy motor, which hopefully means it'll last awhile. I'll be looking into what other products this company has to offer, because while they are inexpensive compared to many others, they really seem to have the pulse of what is needed and provide it at a reasonable price! P.S. - this is designed as a desk top unit, and it works nicely in that way.

The Pure Enrichment PureZone Halo is my first air purifier and I was very excited to try this out. Packaging was simple and straight to the point. Inside came the purifier as well as the usual paperwork (be sure to read the instructions). It is suggested for use with a room that's about 100 square feet and ideally that should work for a small office or bedroom with no issues. Setting the Halo up was a breeze, you just need to remove the front cover and take the filter out of the plastic before replacing it with the black side facing you and then replacing the front cover. Following this plug it into a power outlet and you are good to go. I must point out that the filter for this unit is dual in nature. It has a true HEPA filter combined with an activated carbon filter which according to Pure Enrichment should capture 99.97% of pollen, dust, pet dander, smoke, mold spores etc . According to the manual this filter should last 6 months but I’m sure it can last longer based on your use. The Halo’s touch capacitive controls are all located on the top, going from left to right you have ON/Off, Light (I,II,Sleep), Fan(I,II,III) and Timer(2h, 4h, 8h) controls. By default when you turn on the Halo you are in Fan speed and Light level 1. I find the warm blue glow from the light very soothing and level 1 works best for me as I find level II too bright. There isn't a dedicated off button for the light but setting the light setting to sleep will turn off the light while the device continues to work for whatever time you have set. The Halo is also very quiet , in fact I only notice fan noise when the speed is set to level III. I must also point out how sensitive the controls are. A causal touch across any one of the controls may change your desired settings, so just be mindful. Finally, I was most impressed by how the air quality changed in the room I set this up in. Over the week I have used the product (8 hours daily on level II fan speed), not only did I notice a significant reduction is general dust on screens and furniture etc but I also noticed that the air felt more “light” and crisp to breathe. I also tested eating food with very strong lingering scents within the room and I can report that it definitely shortens the time food scents stay around, so I will assume it will work for other scents well. For my first air purifier, the Halo has done a tremendous job with its compact size and simple circular design and I definitely recommend it.

This Pure Enrichment - PureZone Halo air purifier is a necessary device at home/ office to have better breathing. For those with allergies and Ashma “like me,” look for better air quality to improve their breathing. This air purifier features a HEPA air filter that can remove dust, pollen, and airborne particles. Design: Very sleek and modern design “futuristic” with halo light that changes from high to low to sleep mode. Compact and perfect to be placed on the countertop or desk, and light at night is relaxing. Performance: Has three fan speed, and it is very quiet when set to low fan speed and high when set to a higher speed. Personally, it is doing very well, and usually, I put it to low speed. From observing its performance, I noticed that the amount of dust coming from my backyard becomes less, which means this device is picking it up. However, the downside is the lack of air quality indicator and smartphone app support that should be useful to monitor the air quality and ensure the functionality of this device is effective. I took one star due to that lacking. I had to use my Dyson air purifier to monitor the functionality of this PureZone air filter through the smartphone app. It did show that air quality is getting better, so it is effective. Also, I was able to feel that my breathing is getting better when the machine is working. Happy to get this air purifier. Note: Make sure to remove the protective plastic strips before operating the machine.

This is the best air purifier ever it works amazing

The PureZone Halo Air Purifier filters are readily available online when I checked. (this unit is PEAIRDSK which requires the PEADFIL filter).

This PureZone Halo is a wonderful supplement for a guest bedroom, or a child’s room or maybe send it off to college with a youngster.
