Levoit Vital 100S

“No, absolutely not. I see it selling for around $85 on Amazon (and other retailers). It was replaced with the Core 300-S which lets you control it via an app on your phone. The updated model is also lighter and more powerful. But, it sells for around $150, so the original Core 300 is now much cheaper. But now Levoit has a whole new line - the Vital series, that is better than the Core series. The Vital 100S is a flatter design, is about the same weight as the Core 300, and designed for a similar small room. It is as easy to move from room to room if you have to. But, the filter design is better. You can remove and clean the outer screen - where on the Core series the outer screen is built in to the filter itself. It is also more efficient. All of the Core series air purifiers are no longer considered HEPA compliant because so much air leaks around the filter. But, the Vital series doesn't have that problem. The 100S is around $100. For a living room you might want to consider the big brother of the 100S - the Vital 200S. It is the same design, but twice the cleaning air flow so it can be effective in bigger spaces. It is $189, but I notice that on Amazon you can check a box to use a $20 off coupon to bring the price down to $169. For work, I would go with something smaller. Trying to purify all the air in the office just isn't going to happen. You just want to improve the air directly around you. The best unit for that task would probably be the IQAir Atem Desk Air Purifier. It has great filters, is small, and blows pure air directly towards you face. But, it is around $400. A budget option would be the Levoit Core Mini - a much smaller version of the Core 300. That would be a good size for a desk or cubical, is easily portable, and can run on rechargeable batteries if you are not near an outlet. I use one in my car. It is about $50.”
