Winix 5300-2 Air Purifier with True HEPA, PlasmaWave and Odor Reducing Carbon Filter

We bought this purifier in 2019 to help improve the air quality in an apartment. The building was older and had a ventilation system that, during the winter, would pull cooking smells, smoke, and other odors into our living space. The overall timing turned out to be fortuitous since we ended up spending a lot more time indoors when the pandemic kicked off a year later.The immediate effect of the purifier was noticeable. Unwanted odors were improved, there was less dust in the air, and we experienced fewer allergy symptoms. Especially since we were in a smaller space (~600 sq ft), this thing really did a great job, even staying on its low setting. It was great piece of mind knowing the air quality was a bit better for our newborn, too.We’ve since moved into a larger house and this thing is still humming along in our living room. I’m sure it’s less effective in such a large open space, but it’s positioned near our A/C air return, so it’s cleaning up a lot of the air as the A/C circulates air through the whole house. It has remained quiet and effective. I just vacuum out the dust shield every couple weeks, replace or vacuum out the charcoal filter every few months, and change the HEPA filter out annually.Overall, I don’t think you can beat this for the price. I like that it doesn’t have a remote, an app, and other extraneous things when all I need is cleaner air. I’ll likely upgrade to something larger at some point, but I’ve been super happy with this little guy for over 5 years now.

I studied this and others before purchase. @ NingN photo review on energy cost sold me too. It's been a year after purchase and it's still kicking butt. Helped with allergy proofing my room. Since my roommates have cats. I'm allergic to dust all year and other thing are seasonal. I can't eradicate the dust. So with my every day battle I'm glad I have this purifier as my weapon of choice. I love this product so much I bought my mom one too!Scent: doesn't have one but can help with catching farts. Me and my boyfriend laugh the first time he farted and the color of the air quality detector went from blue to red.Air quality: cleaner but a bit drying. Cool/ Cold air. I'm okay with this since I live in Houston and the air is always humid. An the cool air is a bonus in th is texas heat. Even made a pocket/ bubble of air using my blanket. Step 1 place next to bed. Step 2 place cover over machine and bed. Step 3 lay under cover, pushing edges under body and edges of machine.Noise level: one sleep setting barely noticeable. Highest setting is as loud as hearing someone closing the front door of the house, toilet flush with bathroom door closed, or even the A/C in Car on high. Look it's not loud like a vacuum so you pet will me fine.Maintenance: simple the diagram is on the inside of product. When cleaning the pre- filter (mesh) I wipe/peel layer of dust with hand weekly. Like you would with dust catcher in dryers. Once a month I fill bath tub with warm water and pour it in a quarter size dish soap. Place the filter in and shake it back in forth on both sides. Drain the water in tub then rinse. Place it to dry for 24hrs then pop it back in. Voila it's good as new.Cost: economic. Comes with extra filters. When you do have to replace there's off brand options or price match through walmart and target for originals. I keep mine on 24 hrs a day only because it's in my room but they have automatic shutoff times 1hr, 4hr, and 8hr.Overall to me it was a priceless investment. Hope this review helps anyone.

If you suffer from allergies, this filter is so worth the money. It's made a major difference in my home this allergy season.It shows a color-coded light that identifies when it's sensed contaminates and what level cleaning is underway: Blue, Orange, Red. I know it's accurate, because if I open the door for any length of time it turns orange. I'm a rather poor cook, and when it gets the least bit smokey inside it turns orange. I usually turn it off when I'm cooking. However, one night I filled the place with smoke, and this unit cleared the air in about two minutes, all the while display the bright red "What are you doing" light.When I first powered this up, it was red for a few hours, letting me know how contaminated the air was in my home without this device.If I leave this on for the day, when I return at night the air has a slight izonization smell... sort of like after a nearby lightening strike; which I'm guessing means it's been doing its job.The filers are kind of pricey, but couldn't even watch TV because my eyes were so watery before I got this unit; so it was worth it.First, there's a simple screen to block the big stuff. I just pop-this out and spray it was the water hose and it's clean in seconds. Behind that screen, there's a 30-day charcoal filter. These aren't reusable, but the unit comes with three of them. That's because the third filter is the micro one, which lasts for 90 days. So you use the three charcoal filters for 90 days, then replace the micro filer as well. An new filter kits comes with another three charcoal and one micro filter, so you're good for another 90 days.After about 45 days my allergies were starting to get bad again, then I remembered I hadn't replaced the 30-day charcoal filter. As soon as I did the air improved.It's pretty quiet. I don't really notice it's running unless I've got it on the maximum speed. At that speed it's loud enough to interfere with hearing the TV, but it's really cranking-out the air as well.Most of the time, I leave it in the auto mode. The sensor works very well, knowing when to kick-in and when to stay dormant.I'm considering getting another for the office.
