So happy with the purchase, its worth the price. It’s working so well and app is so easy to connect.

I have been using it for a couple of months now it is really good. But i wish if it had like a diffuser in it to make the place smell good

It is really fabulous 👌

Helped with my allergies but we haven’t had it that long so can’t be too sure if it’ll work well long term

The best saved my cats life and my house as a fire stared in my house while I was away and the alarm didn't work but thus work and send me an alert sms about the quality of the air in my house I came back home running and succeed to save my cat and home

Too good and easy to install

The filter worked too well that I had it exchanged for a bigger option.

Works fine, thanks for delivering good product. Continue your good service.

Genuine Levoit Vital 100S filter is noticeably better than cheap knockoffs. Here’s why it matters. I’ve gone through a couple of third party compatible replacement filters for my Levoit Vital 100S air purifier and they always left me disappointed. This official Levoit replacement (part number Vital 100S-RF) is in a completely different league and I want to explain exactly why so you can make an informed decision before defaulting to the cheapest option on Amazon. The Activated Carbon is the Real Difference: The single biggest gap between this genuine filter and the knockoffs is the activated carbon layer. The genuine Levoit filter uses substantial pellet style activated carbon that actually absorbs odors, VOCs, smoke, and cooking smells. The knockoffs I’ve tried usually just have a thin carbon coated sheet or a light dusting of carbon powder that does almost nothing after the first week or two. You can physically feel the difference in weight when you hold them side by side. The genuine filter is noticeably heavier, and if you shake it gently you can hear and feel the carbon pellets inside. The cheap ones feel hollow by comparison. This matters because activated carbon works through adsorption, meaning gas molecules physically bind to the surface area of the carbon. Pellet style carbon has dramatically more surface area than a thin sprayed coating. A flat carbon sheet might technically contain activated carbon, but it saturates almost immediately in a home with pets, cooking, or any real odor sources. The pellets last months. That’s not marketing, it’s just how the chemistry works. After swapping in this genuine filter, lingering pet odors and kitchen smells cleared out within a few hours instead of hanging around for days like they did with the generics. My air quality readings through the VeSync app showed improvements faster and the purifier didn’t need to run on high nearly as often. It actually settles into auto mode and stays quiet, which tells me the sensor is detecting genuinely cleaner air rather than constantly ramping up to compensate for a filter that isn’t pulling its weight. HEPA Performance: The HEPA layer on the genuine filter feels denser and more tightly constructed than the third party versions I’ve handled. Levoit rates it at 99.97% particle capture down to 0.3 microns, which is the standard for true HEPA filtration. The generic filters all claim similar numbers on their listings, but the actual media quality varies wildly. I noticed more fine dust settling on surfaces around the house when running the knockoff filters, which stopped once I switched back to genuine. That’s not a controlled lab test obviously, but over several months of daily use the difference was consistent enough that I trust what I’m seeing. One thing worth mentioning: the genuine filter supports Levoit’s HEPA grade performance during Sleep Mode, which keeps filtration efficient while running at 26dB or less. Levoit says this has been independently tested to IEST RP C001.7 standards. I can’t verify the lab data myself, but I can say the purifier is effectively silent on sleep mode and the air still smells clean in the morning. With one of the generics I tried, sleep mode felt like it wasn’t doing much of anything. Fit and Build Quality: The genuine filter drops in with a perfect fit. No gaps around the edges, no rattling, and the magnetic front cover snaps shut cleanly every time. This sounds minor but it actually matters for filtration. Any gap between the filter and the housing is a bypass path where unfiltered air gets pulled straight through without being cleaned. Two of the three generic filters I’ve used had slightly loose fits that left small gaps at the corners. One even had the frame slightly warped out of the box. You could hear a faint whistling sound from the air bypass on that one. The washable pre-filter layer on the genuine unit is also well constructed. It peels off easily for cleaning, traps pet hair and large dust before it hits the HEPA media, and goes right back on without fuss. Keeping this clean regularly extends the life of the main filter significantly. Filter Life and Replacement Timing: Levoit recommends replacing every 6 to 8 months depending on usage and environment. The Vital 100S has a built-in filter life indicator that tracks usage and reminds you when it’s time to swap. One detail most people don’t realize: that indicator algorithm is calibrated for genuine filters. When you use a third party filter, the replacement timing may not be accurate since the generic media could be saturating faster or slower than what the sensor expects. It’s a small thing but worth knowing if you rely on the indicator rather than checking the filter manually. In my home with two cats and regular cooking, I get a solid 7 months out of the genuine filter before the indicator goes off and I start noticing reduced performance. The generics I used started losing their odor absorption noticeably around month 3, even though the HEPA side was probably still functional. That shorter effective lifespan cuts into the cost savings pretty quickly. Cost Perspective: Yes, the genuine filter costs more upfront than a two pack of generics. That’s the main reason people go third party and I don’t blame anyone for trying it. I did the same thing. But after running both, the math doesn’t favor the generics as much as it seems. If a generic filter effectively stops handling odors at 3 months and you end up swapping it twice in the time one genuine filter would last, you’re spending similar money for worse performance. And you’re putting extra wear on the purifier motor since it has to run harder to compensate for a partially clogged or poorly fitting filter. If your main concern is just particulate (dust, pollen, dander) and you don’t care about odors, a decent generic filter might be acceptable. But if you’re dealing with pet smells, cooking odors, smoke, or VOCs, the carbon quality on the genuine filter is where the real value lives. That’s the part the generics consistently cheap out on. Multiple Filter Options: One thing I appreciate about the genuine Levoit line is that they offer specialized variants beyond the standard filter. There’s a Pet Allergy version optimized for fur and pet odors, a Toxin Absorber version focused on VOCs and smog, and a Smoke Remover variant for wildfire smoke and heavy particulate. I haven’t tried all of them but it’s nice to have options tailored to specific use cases rather than a one size fits all approach. The generics don’t offer anything like this. Also worth noting that Levoit uses FSC certified wood sourced activated carbon in the genuine filters, which is a minor sustainability detail but shows some thought went into material sourcing. Who This is For: If you own a Vital 100S or 100S-P and you’ve been buying the cheapest compatible filter you can find, I’d encourage you to try one genuine replacement and compare for yourself. The difference is most obvious if you have pets, cook regularly, or deal with any kind of persistent household odors. If you’re in a clean environment with minimal odor sources and just need basic dust and pollen filtration, you might get away with generics. But for anything beyond that, the genuine filter earns its price. I’ve been running this filter for a few months now in a home with two cats and regular cooking and it’s still going strong. The carbon is still absorbing odors effectively and the HEPA layer shows no signs of premature clogging. I’ll be sticking with genuine Levoit filters from now on. Highly recommended if you want your Vital 100S to keep performing at its best.

I've had it a week and it's going well. I really don't get how it can be called quiet though. It could wake the dead on number 4 !

Love CV this. Does a great job filtering our air

I saw nothing in the description of what wifi it only works on and unfortunately this makes this expensive buy really not worth it. Surely devices in today's day and age we would not have to worry about 2.4ghz and 5ghz. Both should be an easy option

Works as described!!! It improves the air quality in my home!
