This Filter is very easy to change. I just did that and the used filter looked very different in color with all the sediments it trapped. I am happy with the performance.

This replaced an older (wheezing) purifier.

It is easy to clean, and the buttons are clearly labeled.

It is not really quiet, but the noise is very steady and I like it.  It masks noises from the street, but does not interfere with a conversation.

I've owned an older version of this model for over 2 years. It works, it's easy to clean and maintain. If you pay attention to the filter light there's no reason you should have to buy replacement anything. Just open it up and vacuum the pre-filter. It's well designed and simple to use.

It is a little noisy but there's no way to move that much air through a small space without creating noise. I prefer to think of it as an air filter and a white noise machine.

Did I mention it works? Smoke, smells, particles, etc.

I liked it so much I bought one for my office as well.

Simple shower head and easy to replace filter.  Good quality.

This is a good deal and the life indicator strip means I don't have to keep track of when the filter was replaced.

The product came in just a few days.  It was simple to set up, taking no more than five minutes.  This filter takes out the taste and odor that my water has.  It is a little cumbersome at the sink side at times but is well worth the money. Much less annoying than those that hang from the faucet.

This filter does a good job of clearing the water. My one complaint? The filter seems to clog easily. However, it is easy to take apart and put back together. Makes cleaning and clearing clogs, quick and painless.

The water is crystal clear and I have no deaths. Not having to clean and replace filter materials is a pleasure. I do partial water changes weekly,however. I certainly would recommend this filter.

This filter is very easy to install on a faucet. Switching between filtered and non-filtered water could not be easier.  The whole unit is sturdy, easy to use and does not interfere with the faucet being needed for normal use.  Makes filling pots with filtered water for cooking a breeze!

These are clear and easy to install. they come with dust removers which are large blue stickers used to remove any stray dust from the screen before application. and it comes with cleaning stickers where if you miss a stray piece of dust you can use it to lift away the protector and then use it to stick to the affected dust partical that causes any bubbles and removes it from the sticky side of the protector then you can easily place the cover back on the screen that was lifted up and the bubble disappears. its 100% clear without the weird oil rainbow color from the glue. and its a direct fit with a little room on the edges so its not hard to get it lined up.

THESE FILTER ARE EXACTLY AS DESCRIBED.  I HAD TO ENLARGE THE HOLE, WHICH WAS EASY TO DO WITH SCISSORS TO FIT MY PARTICULAR FILTER.  THESE HAVE BEEN USE FOR 3 WEEKS NOW AND HAVE CLEARED MY AQUARIUM BEAUTIFULLY.

I recently purchased a new filter set for my inherited Shark Navigator Lift-Away and thought it would be a good idea to invest in a new HEPA filter as well. The HEPA filter is the last filtration step before air that has been sucked in is forced back out. Its main function is to collect he  dust and allergens sucked in that you do not see as well. It sits inside a plastic vent cover just below vacuum canister. Replacement is quick and convenient. On the bottom of the vent there is a latch that you apply pressure to while pulling up on. It snaps off fairly easy so a lot of pressure isn't needed. Then slide down to where top pegs release and slide out so the old HEPA filter is visible. In the center of the old filter there is a tab for pulling it out. Simply slide new filter back in and replace vent cover. I always hold filter back with my hand so pegs are easier to pop back in, then snap latch until it clicks and you are ready to go. In between uses filter can be slightly tapped to remove some of the particles inside and prolong life of filter. I always like to replace about two to three times a year. Before replacing there was a strong dust smell when vacuuming and I have noticed that the smell has since dissipated. I was awarded the opportunity to purchase this product at a discounted price for test use in trade for a fair and unbiased opinion.

I've been looking for a new air purifier for almost a year now, doing research here and there trying to find a unit that meets all the requirments I'm looking for. I need a unit that's for a larger room, has an auto feature, has good priced replacement filters, and looks good to match my home decor. A recent 80,000 acre fire hastened my research due to the thick blanket of smoke that blanket the area (and still is) every morning. With all things considered, the Winix 5500-2 met all my requiements.

The unit arrived promptly and unpackaging was an ease. I literally had it set up ans running in about 5 minutes. The body is a hard, matte black plastic that feels sturdy and durable. The front panel is easy to remove, and secures to the unit via a clever magnetic clasp that is secure, yet simple to remove to access your prefilter for bi weekly cleaning and hepa/carbon filter replacement. There are 3 filters in total, and they fit snugly inside the filter chamber, amd ate secured in with the prefilter that snaps firmly into place.
The control panel at the top is intuituve and user friendly. The buttons are clearly marked and visual ques explain what each button does taking out any guesswork as to what they do. A stylish indicator light bar runs along the bottom of the control panel indicating the level of air cleanliness with a 3 color scheme...green for clean, orange for okay, and red for bad. You can manually run the machine on 4 fan settings, or choose auto mode and let the machine choose the settings based on the data colected from the sensor. This means hands off operation. There's a night mode that will set the fan to its lowest setting to cut down on noise, and also dim all lights on the panel. This night mode will set automatically if you have the auto mode set on the unit, a light sensor will detect (or not detect) any light in the room and go into night mode. A filter change indicator light also is on the control panel. According to what i've researched, the hepa filter should last approx 1 year. It also comes with a remote control with a battery preinstalled. I don't plan on using it, but if that's your thing, it's there.
This is the quietest air purifier I've ever owned. On level 1, it's almost undetectable, and even on level 4 turbo mode, it's no louder than a standing floor fan on high. This was a very pleasant surprise.
It cleans the air well. I'm currently using it in my 350 sq ft bedroom. I don't have the equipment to test it, but per their website I should be getting at least 4 air changes per hour which is the amount of air exchanges you need for allergies and serious air purification. I've had no smoke smell AT ALL in the bedroom when I run this with the door shut to the rest of the home and it was initially startling to walk from the bedroom into the rest of the home after the first night of using it.
This unit has more than exceeded my expecations ans meets all the things I was looking for in an air purifier. I plan on purchasing 2 more of these when money permits for my combined kitchen/dining/living room area that totals 700 sq ft. I can place these at opposite sides of the area and get more than ample coverage. I would highly reccomend this unit. For the price and the feature list, this just can't be beat. The cost is low, the replacement filters don't cost an arm and a leg, it covers a large area, and you get a lot of features.

Works well and easy to clean. the filter changed color after a few uses. But for this price, it's acceptable. Other than that I like it.

This is a great respirator which is being used mostly in wood working. Fits snugly, is easy to don and doft and clean. Other filters are available, some I have used for solvents and little if any odor noticeable. A good safety item at a fair price that is not unduly inconvenient.
