Easily portable and highly effective
This purifier came with everything needed for operation. I like manufacturers who pack things so the consumer gets exactly what he needs at every step of putting the item into operation. The instruction manual was right on top in the box. Everything else was neatly packaged for optimum safety and easy assembly. The filters need to be inserted inside the purifier. They were sealed for optimum efficiency when you begin using them. The top of the purifier is easily removed to insert the filters. The bottom has an interesting design. It only needs to be removed when you remove the battery at the end of the life of the purifier. The instructions say to turn the purifier over and just lift the bottom. I found that the bottom is held on the purifier with four magnets that attach themselves to the four screws that hold the cover on the battery compartment. A small screw driver is included in the package for removing that cover. They thought of everything for the entire life cycle of the purifier. A person who attends some meetings with me often has coughing fits. It is not related to COVID, but evidently related to something in the air. I easily carried this purifier to a meeting and the person was impressed, since there were no coughing fits during the meeting. I allowed the person to borrow the purifier until the next meeting. The person immediately looked for where to purchase one.

Good Air Quality
This air purifier does work good and instructions on how to install the Hepa filter and the NCCO (Nano Filter) are real easy. Also the rest of the instructions on how to turn the machine on & off and from low power to higher power are all good. The sound of the machine on low is very good, while on the higher power - you might have to get adjusted to it. I can hear it from two room over while on high power. All of this is good but the items that I am not satisfied on the instructions are the replacement of the filters. Per the instructions it should be every 6 to 18 months but it says also every 3000 hours - which is every 4 months. Also the instructions do not show part numbers for the replacement filters ( I had to find those online). The other most important item is the built-in battery if it goes out ( & you are using the unit as a portable& not plugging it into your outlet) - the instructions show you how to remove the battery by cutting the wires but there does not seem to be any replacement battery (even searching online). In calling the company's phone number in the instructions -the message is for a car company & not for this manufacturer's customer service or its distributor. So not sure if you can ever replace the built-in battery or not. I'd recommend it for the good air it gives but not sure about recommending it if someone will use it mostly as a portable unit & they might use up the battery.

Quiet air purifier
We just received this air purifier and I love how quiet and portable it is! It was easy to assemble, but I still don't know what the white strap is for. Maybe I missed something in the instructions. In any case, it is very lightweight and you can barely hear it when it is on. I don't know how well it works yet, because after using it for a few days the filter and ceramic beads are still clean. It will be nice to take this with me when I travel or camp in our trailer.

Great medical grade air purifier for on the go or a desktop area
This is a medical grade air filter for when you need your surrounding air scrubbed clean. It uses a 3 stage air filter system-1st is an oxygen generator-2nd is a HEPA filter-3rd is an NCCO filter(Nano-confined-catalytic-oxidantion) simply put kinda shakes the pollutants and breaks them down to carbon dioxide. It eliminates pollen,microbugs,dust,mold bacteria and decomposes things like VOC’s,viruses,odors etc. I’ve been using this compact version in my garage for things like smoke,VOC’s and misc bad odors and it works really well. You can keep it plugged in or take with you(as it has a lithium battery for portable power). It has a nice carry handle for easy on the go situations and I used it in my truck when a friend wanted to smoke a cigarette and I didn’t want the stale odor it leaves behind. It worked very well and left my truck with no odor.

A must have in today's homes.
I saw this Westinghouse Portable Medical Grade Patented True-HEPA 11, 3-Stage Air Purifier, Light Beige and thought it would be a useful tool during the pandemic. Since it kills viruses by using positive Charged Oxygen Radicals that attack these trapped pollutants and render them inert and unable to reproduce or affect human health, I felt this is a must-have. In homes where people gather, this unit will give additional protection along with mask wearing. I also have family member suffering from COPD and this gem will help clean the air her room aiding in her breathing. The unit is compact and very quiet allowing to be placed on a nightstand for easy access. The unit operates up to 24 hours on a single charge-which is convenient for when the power goes out or where a power source is unavailable. I recommend this purifier for any home that have concerns or issues where cleaner and safer air is warranted. A very nice product.

My mother-in-law has very serious allergy to pollen and even tiny dust inside the house. This product is something that can really help her to just get clean and filtered air. The air purifier is very well made. It was easy to install the filters (there are two, one is for filtering particles and the other is some sort of active material that cleans the air). It is also very easy to operate, once press on the power button activate the purifier, pressing it again would adjust the internal fan to a higher level, and one more pressure powers off the purifier.

This Westinghouse NCCO Personal Air Purifier Model SP6440 is exceptionally small and compact. It has a battery that lasts for just over 2 hours on low fan. The battery recharges in about 3 hours with the included USB power brick; and it can operate on just the power brick. In addition to the leather handle strap an adjustable woven strap with clips is included to allow it to be attached to something else, like a headboard or bed post. The back is attached magnetically, so just pry it loose with your fingernails to get it to come off. It looks like you can leave the back off as there are rubber feet exposed when it is removed. Operation is very quiet and it seems to move quite a bit of air to be so quiet. We had a spoiled tuber that stunk up the pantry and kitchen and this air purifier got rid of the stink in about an hour. The manual's instructions do not include installing the woven strap, so look at my picture of it installed (I think that is right). The English section of the manual was written by someone for which English is a second language. The manual also lists 2-letter error codes that I cannot see how the air purifier shows them as it does not have a display! I do not see how to purchase replacement parts - the HEPA filter and the NCCO Reactor do have life spans and should be replaced every 6-18 months depending on operating environment. The manual says to dispose of the unit you must remove the lithium battery and dispose of it separately; but to do that you'll need a special triangle-shaped screwdriver/tool that is NOT included in the package. The included magnetic screwdriver is a #1 Phillips.

I am extremely hypersensitive to tree pollens. Where I live, all season except for summer expose me to high amounts of tree pollens when I leave the house. Even in the house with great filtration, I still am in misery for much of the year. I've had air purifiers before but I had to have one in each room. I really like that this unit is portable and I can carry it with me both in the house and when I go somewhere. The technology is new for home use and it seems to make a difference in how much I am effected by pollen. It has filters, etc. that will need to be changed. I am hoping that the filters will be easy to find when I need a replacement.

This is about a foot square and about 6 inches deep. It's light and quiet- at least on the low fan speed setting. There is a hepa filter in addition to the FCCO beads filter. The cool thing is that it has a rechargeable battery on board, so you can charge it at home and take it with you wherever you want to go. The leather strap is all we've needed, but there is a white nylon strap included as well for shoulder carry. The start button LED is white for low speed fan and blue for high speed. The LED blinks when the unit is plugged in and charging. This is really a well thought-out device and a nice insurance policy for clean air.

Im very impressed with this technology thats now available to the public. I have asthma and environmental lung disease so i have hepa air purifiers in every room of my house. This one sits on my night table. I can absolutely tell a difference. The ncco filter destroys viruses. The hepa catches pollen. Dust. Dandruff. Mold. I love the rechargeable capability. Replacement filters are expensive but its definitely worth every cent. Im taking it to the mountains for my 4th of July vacation this year.
