SILVERONYX Air Purifier for Home Large Room – Covers Up to 500 Sq Ft, 5-in-1 HEPA Filter System for Allergies, Pets, Smoke, Remove Dust & Odor – Quiet Sleep Mode, High Filtration Efficiency – Black

I just received this bad boy a couple days ago, so I will hopefully remember to give an update in a couple weeks. A few years ago I found out the reason I was getting sick all the time is because I am allergic to dogs and unfortunately have two bulldog fur babies I love very much who shed A LOT and slobber more! My only option after finding out I was allergic to dogs was to hug my dogs, suck it up, and accept a life full of a stuffy nose, watery eyes, and severe sinus congestion.Not sure why it took me 4 years later, but I just recently thought to myself I wonder if an air purifier would help. So I started looking into air purifiers and I researched A TON of them for a few weeks. I didn't want to spend $300 on one, but also wanted one that worked. We have a smaller house, just barely over 1,000 square feet. It is mostly carpeted, besides the kitchen and bathroom, so the pet smell can get bad no matter how many carpet cleanings or how much vacuuming we do. The house is also EXTREMLY dusty. We just had the vents cleaned out and $450 later the dust was still just as bad. I will dust the house and within 2-3 days everything is covered in dust again. When the sun shines in I can see the particles floating around.I was debating between this one and the extra large room Honeywell purifier. It seemed like they were neck and neck for the most part with the reviews and performance, except this one is $70 cheaper. The things that I liked about this one that the Honeywell didn't offer, from what I could tell, was the UV light option and the auto option.Once I turned it on I tested out the auto setting right away. This is a setting that tells the unit to increase the level of "purifying" based on how bad the air quality is. I turned it on and lit a candle, I blew the candle out and set it next to the purifier, this thing instantly kicked into high gear and within a minute had cleaned the air and went back down to level 1. Pretty awesome. I have noticed my air quality is typically around the 13-16 level range for quality and today after I was done getting ready and spraying my crazy curly hair with hair spray I opened up the bathroom door (which is about 10 feet from the purifier currently) and the air quality got worse in the 50s, this little guy recognized it and kicked into level 2 to clean out the air.I am just amazed at how intuitive they can make a product for such an amazing price.I have noticed the musty dog smell is already getting a little better in the house and I am only on day 2. I will say, I have NOT noticed improvement on my allergy symptoms yet, but the purifier is set up in the family room and I just bring it to my bedroom at night. So in it's defense, it isn't working all day in my bedroom. You may think I am crazy being allergic to dogs and letting them sleep in my room inches from my face, but how can you say no to a squishy bulldog face? You can't.The noise level. I am an extremely light sleeper and I have to have white noise in order to sleep at all. I had a REALLY old loud air purifier that I would run just for the noise because I get too cold with a fan. On level one (which so far from the last two days and if it is set on auto the machines runs on that level 98% of the time) you cannot even tell it's on and same for level 2 and level 3 you will start to notice the noise. I actually like that level 5 is kind of loud because it helps me sleep, but to run it in the family room on level 5 don't expect to hear the TV well or have a conversation easily. I also like that there is an option to completely turn off all lights on the machine while it is running to keep the room dark while you sleep.Hope this helps! I will try to remember to review on my allergies once I buy another one just for the bedroom to run all day to make the review fair!

I really like this. It works great. Especially on automatic. I plan to buy a couple more soon.

The little air purifier does a great job of cleaning the air quietly. Changing filters is easy, too.

This review is for the almost identical twins, the Silver Onyx and the OdorStop OSAP5 (and why I like the OSAP5 better)I'm impressed with this type of tower style air purifier. It takes up much less space than comparable flat filter purifiers like the Hathaspace or the Winix. Other comparable tower style air purifiers like the GermGardian have flat long rectangular filters. This one has a barrel type HEPA filter that also has active carbon at the final stage. It filters out the micro-particles first then eliminates the odors. It's backwards from the way most others do it but I think it works better. After that, the Silver Onyx / OSAP5 sterilizes the filtered air with UV light (if the option is turned on) and spits out negative ions (if the option is turned on) that attach to dirty air molecules and force them down (preferably into the filter and not your carpet). Seeing that both the Silver Onyx and the OdorStop OSAP5 are almost identical, including the fact that they use the same replacement filter, here are the 2 main reasons I like the OSAP5 better.1. The OSAP5 has breather holes 360 degrees all the way around the air inlet maximizing the full potential of the filter. The Silver Onyx only allows air in through the back of the unit hampering it's ability to pull in dirty air from every direction and with less breather holes, it's hampered even more.2. The OSAP5 blows the purified air straight up. The Silver Onyx has a tapered vent at the top that blows the purified air out at about a 55 degree angle and because of this, the Silver Onyx recirculates it's own purified air way too much.I really enjoy the way these things work and if you want to see another review concerning certain features look for Saved Forever's review of the OSAP5.

We've had two of these units in our house now since December 2019 -- almost 5 years! We burn a wood stove for heat all winter, our summers are dry and dusty, spring is full of pollen. My husband has allergies to dust, pollen, and dander -- I'm bothered by smoke -- and having these little workhorses around (we have two) has made a tremendous difference. They hum along at a steady pace day and night and alert us when air quality is getting poor. They've done triple duty on multiple occasions when wildfire smoke was so bad, we were advised to stay inside for days. They worked HARD hour after hour, and we felt safer, knowing they were doing their job. I'm not typically a review writer, but I was so impressed when I wrote to the company this month after one of our units began acting funny. They immediately responded with incredibly clear, easy instructions for fixing the problem, and my unit is now back to doing its job. We use them every day and I've only had to change the filters 2x since we bought them. (Did I mention we also have a dog?) Cannot say enough good things about this product or the company's customer service.
