LEVOIT Genuine Core 300-P Replacement Filter, Core 300-RF Air Purifier Core300S Filters, Supports HEPA Sleep Mode, High-Efficiency Activated Carbon for Removal of Smoke, Odor, Allergens, Pollen,1 Pack

Why did you pick this product vs others?:This is a refill but its great. It fits my machine which is important. My machine is I would say about a medium sized noise level, however, I bought it to purify the air so I don't really care how loud it is. The size is perfect. Not too big not too small. There is a mechanism, a button, an option, to make it quieter when you're sleeping. The design is pretty boring. But again, I'm OK with that, I bought it to clean the air. I assume that it helps me breathe better because I haven't passed on yet and that's always a good sign. I feel my air is clean and refreshing.

Why did you pick this product vs others?:I have 4 pets, two dogs and two cats! I’m slightly allergic to cats nothing crazy just a little sneeze here and there. But with these air filters i have noticed that my allergies have gone down a lot! They work so well for our family. It’s so small we keep it in our Livingston and no one ever notices it

I've had the Levoit Core 300 for a few years and it works very well, it does a good job controlling dust and odors. The new filter fits perfectly and it has no unusual odors. You turn the filter on on and all you smell is a sweet nothing.Yes I know you can buy much cheaper filters but like with my A/C I buy OEM.

If you have pets or tend to see a lot of dust, I’d recommend vacuuming the outside of the filter every month or two. When I haven’t vacuumed the filter in a while my air purifier tends to be louder which I assume is because it’s working harder. After getting the excess dust off the outside of the filter the air purifier quiets down immediately.Easy to install. Have re-purchased 4x so far as I replace my filters every 6 months.

This filter lasted about a year with almost daily use in our small apartment before we got the red light alert to change it. We don’t have pets and the windows are only open during summer, which could be why it lasted so long. I was tempted to buy a knockoff because it’s cheaper, but decided to stick with the brand with hopes I will get another year again. My biggest issue with this filtration system is that I don’t understand why they can’t make a filter that is reusable. It’s a large piece of plastic and I feel terrible throwing it in the trash.

We really like this air cleaner and the filters seem great too. Lasts about six months. We shop vac ours and clean the unit every few months. Picks up a lot of stuff.

So I have used these, as well as a couple of the similar replacements. I must say, it is worth it to spend the extra on the filter it supposed to have. It makes such a difference in the smell, efficiency, and just better for product. I love my machine,(wish I bought another when they were on sale!!) but when I put a new filter in, after about fourty minutes start to notice such a difference in overall air quality! And I ultimately start feeling better. Don’t save a few bucks when it comes to breathing well!!

Why did you pick this product vs others?:Small design Works well:Have cat allergy.
