Nispirakj150f-c02 Filter Replacement for SilverOnyx 5-speed Air Purifier Model 8541832765 with Ionizer 4-in-1 True HEPA UVC Sanitizer 500 sq ft. 1 Pack

Filter arrived in the white shipping cardboard box and filter looks exact same as original filter. The only concern is that filter was just in simple shipping box, it was not wrapped into sealed plastic bag and the were no documentation or paper slip for the product which was in the box. It was just white shipping box with filter in it. You don't know if this filter was exposed to contaminated areas during shipping or not. That's why I'm giving 4 stars as I'm not sure if it's truly HEPA filter or if it's from reputable manufacture. There is no way I can prove or disprove effectiveness of this filter. I hope it will be effective.

I have 3 air filter machines. One that is a silver onyx and two others that are similar. All needed their filters replaced. They are pretty close to the original filters with a few differences. One being they are not quite the same size. A little smaller than originals plus the filter texture is different but they seem to be working just fine. What I paid for three would have been the cost for one.

It's quiet. We smoke in the house (trying to quit...ugggg)The HEPA filter comes on and turns red everytime that we light a cig. It is a reliable reminder of wanting to quit. It whirs a little louder and beams red and my concious screams to quit right then!I appreciate and love this product for my future health.

They are a bit smaller, but they fit in my Vremi air purifier snugly and well enough to help me avoid spending $45 on two filters from Vremi!

Love this product. Fits my air purifier perfectly. Super easy to install. I faithfully order one every month and it filters cat dander, dust, and any unhealthy particles. Makes an entire room feel fresh. Highly recommendA++++

Just as good as the brand name versions but a lot cheaper. Only difference is they came in a large box individually plastic wrapped instead of each on its own box. And I am completely ok with less throw away packaging.

I have three OderStop air filters using the H13 HEPA filters. These fit just like the originals and the price was quite reasonable. I highly recommend this seller's filters.

I ordered the Nispira filter as a replacement filter for my Silver Onyx air purifier. I works fine and I have not noticed any difference in performance. I will order these again.
