are they washable filters

what kind of filters does it take. Are they washable or do i have to keep buying filters
Asked by: igor
No. The filters are not washable. Winix recommends for you to replace the charcoal pre-filter every 3 months and the Hepa filter every 12 months.

Can the Plasma Wave featured be turned off or is it on all the time?

Asked by: Jan
I keep it off; just hold down for 3-4 seconds and you see the plasma light go off. We don't use as odors are not a concern as much as dust and pet hair.

Rated 4 out of 5 by from Fast Efficient Air Cleaning, Auto Fan Speed, Great Air Quality Control When looking for an air cleaner it's important to size the machine to the area you need to clean and the levels of air pollution you will encounter. This P450 model is good for an area approx 450 square feet, meaning it can do a good job in large rooms or a couple smaller joined rooms. From taking this out of the box to operating the air cleaner will take at best, 20 minutes. It's quite simple to figure out how to use it, and the manual helps you along. You'll get used to it within minutes and then it's intuitive. This comes with four carbon pre-filters and one HEPA filter. The filters push into place inside the machine and should last in an average home about a year before you need to order a new set. Of course if you have a lot of air pollution in your home the filters will clog faster. The machine has a filter change light to let you know when it's time. Filter swaps are fast and easy, taking a few minutes at most. To operate this you'll use the touch screen on the top or the included remote control. In my experience the remote was not very good. If you are more then ten feet from this the remote had spotty reception. I set it to Auto so I'd have no use for the remote anyway. The touch screen was popped loose on my model and I had to snap it back into place. It works fine, but it's still a little bit popped out, I can't get it all the way back in. Since it didn't affect performance or operation I left it alone. You can barely notice it anyway. The settings you can adjust are fan speed in manual mode, from Low (whisper quiet) to Turbo (you can clearly hear it across the room but it's not oppressively loud). You can press the Auto button and the machine will sample air quality on it's own and adjust the fan as needed. When in Auto mode it will also sense when the room is dark and only run on low so as to not wake anyone up. The Plasmawave feature can be turned on and off at will by pressing the Auto button for a few seconds. The air quality gauge will change colors letting you know how polluted your air is. It's pretty sensitive. Even cooking or vacuuming in another room will send it into poor mode and cause it to switch to high fan speed and clean the air for you. I like that. This is a relatively large machine but it fits into most rooms fine. It's about two feet tall and 18 inches wide. If you want it to clean a large space as this one does, it has to be big. So far this has removed almost all the odor of a house full of new carpet. It also removes the odors from a cat litter box within a few minutes of the cat using the box and has kept us sneeze free with the ragweed blowing around. I also paint in the basement and they no longer notice the odor on the first floor. Aside from the minor quality control issues with the remote and the control panel popped out, this is still a nice air cleaner and I'd recommend it. It's nearly silent in low mode and I like that one machine can clean so much space. Add in the three year warranty and I'd recommend this air cleaner to others.

Rated 5 out of 5 by from Breathe Easier If there’s one thing in your home that you really want besides clean water, it’s clean air. Over time you can find dirt and dust on your air vents which is a little discomforting as you know you’re breathing that in. Introduce this air cleaner though and it helps you breathe a little easier. The product is a large size but not overwhelmingly so, such that you can fit it in a corner of a room without it being too obtrusive. It has a clean and relatively sleek design, with a nice clear readout control panel on top. As far as operation goes, it is relatively quiet and mostly unnoticeable, especially when it is programmed to not be on at all times. Out of the box the air cleaner is really plug and play and mostly self-explanatory. It’s a little disappointing that it only cleans up to 450 square feet of open air, but that should be at least good enough for a bedroom. I also wish the filters didn’t have to be replaced (I would prefer a more environmental cleanable filter) but overall the product works well.

Rated 4 out of 5 by from Clean air for all Initial set up and directions are very easy to follow. Simple and to the point. The air quality compared to my bedroom air purifier is right on point. I will say with this air purifier, the purified air comes out of the top of the fan (Vs from the side like most of the competitors) I didn't like this at first but the more I used it, the better distribution the air was in the rooms we were in. If you want this to double as a "ceiling fan" of sorts for your room, the air is very well distributed for that. It is somewhat loud when you have it on TURBO mode, but all the other options are very quiet. I highly recommend this. The only issue I have with it is that it is a bit thicker/wider than the competition.

Rated 5 out of 5 by from WOW - Powerful A very powerful and high end looking air purifier. i have 2 black labs so his is a must for any dog owner. I have a Homedics True HEPA air filter large room air purifier which will be taking the back seat on this one. I have a large living room which this is perfect for. the P450 is the biggest of the FresHome Series. It is for rooms up to 450 sq ft. My wife says it sounds like a plane taking off (at the Turbo setting). Has Turbo, High, Med and Quiet. I just set it to AUTO and the Air Quality sensor monitors when it needs to go on. On thing i did like about the Homedics Air Purifier is that it had timing settings. So you could run it for a set amount of time. Comes with 3 Carbon replacement filters. You can buy an extra set of filters for $89 which should last a year. Setup time is less than 10 mins from opening box to using. Comes with a remote so no need to get off the couch. 18.9Wx11.8Dx25.6H

With three small shedding dogs and a hubby with COPD a air purifier was sorely needed. After a month I am very pleased with this appliance. See a significant reduction in dust and hair on furniture and both of us humans are breathing easier. Very quiet 95% of the time and when it does kick on the noise is mild. It fits conveniently next to our sofa and keep it about a foot from the wall. It sets in open family room and kitchen approximately 800 sq feet; very surprised it does a great job with that amount of sq feet. We turn the plasma off and turn whole unit off and unplug over night, runs about 15 hours daily. Definitely recommend; will update as to approximate cost when 1st electric bill arrives.

Rated 5 out of 5 by from Set it and forget it! Super quiet in the living room! We’ve been using this for over two months now and love it. It’s attractive, is of good build quality and is super quiet in the living room. On its lowest setting it’s so quiet that we barely notice it and I mean that. On a 1-10, it’s around a 1. But you can smell the ionized air when you walk by it. On the highest setting it moves a massive amount of air for a room unit. The cleaner can operate manually, or fully automatic. In automatic mode it monitors the air quality and runs only as aggressively as it feels is needed. No need for a noisy fan when the air is already of good quality. Interestingly, at night it chooses to run quietly, even if the air quality would otherwise dictate a higher fan speed. This is promote a peaceful quiet house while sleeping. I know that it’s detecting impurities in the air because the indicator changes whenever my Wife is cooking. One time I was going up and down from the basement a lot (unfinished and old) and the orange lights came on. I like how it will kick in to a higher speed when this happens. Set it and forget it! We don’t use the remote that came with it. It’s just always on and always doing its thing quietly off to the side. I love the smell of the clean air that it puts out. Note that you will have to replace the filter once it’s clogged. I’ve tried using compressed air to blow out the filter from another HEPA unit in the bedroom and that just doesn’t work. This cleaner also uses a carbon pre-filter and comes with 3 of them (according to manual, but mine came with 4). The unit monitors the filter and will let you know when it needs to be replaced. I checked mine the other day and it was still fine after two months. The upstairs seems to be dustier and had that filter completely clogged!

Rated 4 out of 5 by from Good air cleaner, but missing some features. This is a solid 4-star air cleaner! The Winix P450 is the largest model of this series designed for rooms up to 450 sq ft. Very easy set up which is clearly illustrated on the unit. Pretty much just take it out of the box, take off the plastic bag from it and remove the front cover panel to access the filters inside. Take out the filters, remove them from their bags and put them back inside. This step shows you how to access the filters for when it’s time to change to them. Reinstall the front panel and you’re ready to go. Plug in the unit and turn it on. The air cleaner looks great. White and black and has a stylish design. Seems to have good and durable construction. Has a 6 foot long (black) cord that comes out from the back bottom right corner – if you’re facing the unit. The four fan speeds are well spaced. The quiet is indeed quiet and is hard to hear. The Medium is manageable to watch TV with while the High is noticeably louder but does push a lot of air. The Turbo mode however is very loud and pushes a ton of air through! The remote control is small and slim. It has 5 buttons: On / off, increase / decrease fan speed, turbo and auto. The display panel has the following (left to right): ** All the “buttons” are touch sensitive and do not press. - Light sensor - provides normal operation in a well light room. When the room is dark the fan defaults to the quietest mode and all the LEDs on the display dim - Power button - On / Off switch - Speed button - when touched allows you to override the auto mode and select a desired fan speed: Quiet / Medium / High / Turbo - PlasmaWave (top) - just an animated display showing if the feature is turned on or off. You can turn it on or off by holding the Auto button for three seconds (mine works) The PlasmaWave feature is designed to clean the air furthermore on a molecular level - Air Quality (bottom) - displays the quality of the air in the room. Has a backlit display bar from Good (green lights) to Poor (red light) with orange lights in the middle - Auto button - when touched resumes operation to auto - Reset button - to reset entire unit - Check filter light - should light up when it’s time to change the filter - Air Quality Sensor (only works in Auto mode) - will control the fan speed depending on the air quality Pros: - Air quality sensor - Looks good - Good spacing between air speeds - Has a remote - 6 ft cord - Filter access is easy and tool less Cons: - No timer - No wheels or feet - Filters aren’t washable - LED lights are quite bright - Auto mode and Air Quality Sensor are disabled (by Light Sensor) when dark with no override Overall a great air filter that cleans the air well. However it could still use some improvements. I wish there was a manual override button to turn the light sensor off. When it’s dark in the room the light sensor dims the lights and automatically sets the air speed to quiet regardless of the air quality in the room. Sure, you could still manually control it and override the fan speed if necessary, but that defeats the Auto setting. Also, wish the unit had wheels or feet as it’s a bit wobbly without them. The lack of timer is also a disappointment. I cannot comment on pollen control as I do not have allergies. But I do have a cat in the house and it certainly helps eliminate the smell from the litter box. This is my first Air Cleaner and I am happy with is so far.
