Great replacement filter if you don't won't to pay for the OEM air filter from Mercedes. I've had it install for a few months now and had no issues with it. Noticed no change in performance or driving ability. Great buy for the money.

Went to Home Depot and they wanted about $50 for one filter. Ordered 2 from you and with shipping cost around $35. The filter appears to be identical and works fine as far as I can tell.
Thank you for the great produce at a great price. I heartily recommend these replacement filters.

Good quality filter similar to OEM, but at an affordable price.

Filters are a total ripoff.

The water filter needs replacement way too often, and is ridiculously overpriced, and can be hard to find. Otherwise, I would give it 4 stars. Lost one star for a leak that required a service call. The tech showed me it was a design defect, and he knew the fix.

Absent those two complaints, we like it a lot. Just hope it lasts.

Got this filter to replace an older one. Works fine with NO problems. I found this will also accept standard size Culligan water filters from your local Ace Hardware store which makes replacing filters painless.

A note to all the others who complained this unit leaks:
What you need to do is put a thin film of plumbers grease on the gaskets of the filter, the spout and the o-ring seal of the main unit so when you hand tighten it there will be no leaks at all. You can also use a Culligan filter wrench to open it up for replacing the filter. You can get both at your local hardware store for cheap.

Very happy with the filter, especially for the price paid.

I love these cheapo Filters because regardless of the brand the units need to be replaced.  I will probably order again if the shipping and price is right.

Works great at a great price.

A little over a year ago, we purchased a new AC/heating system. As part of this installation, we now need these new larger accordion style filters. When the installation team showed us the new filter, they told us we would need to replace the filter every quarter. I then asked what the price is and where I could purchase these filters and was told I could purchase them directly from the installer at a rate of around $60. Initially I didn't think much of it... I mean, we just spent a ton of money on a new AC/heating system, so what's $60 at this point. I luckily decided to hold off on purchasing any extra filters at that time.

Later that day I checked Amazon and was able to find the exact same filter for far less, thus I've purchased a couple filters directly from Amazon.

The filter is easy to switch out and does a great job. To be honest, I was actually quite surprised at how easy and how quickly I was able to make the switch. I've also discovered that there is no need to replace the air filter every 4 months (every quarter). In fact, we waited an entire year before replacing our filter and the air filter still looked in great shape. We also have a yellow lab dog and two kids, so I think you'll be in good shape delaying replacement unless you're doing a lot of construction work in your house.

Lastly and most importantly, we've noticed a decrease in dust and allergens in our house and have been breathing much better since the switch to our new system.

I definitely recommend this air filter and think you'll be hard-pressed to find this filter for cheaper than what you can find it on Amazon.

If you found my review helpful, please let me know below. Thank you for taking the time to read.

Good replacement filter for my Culligan faucet filter.  It is a good price too, several dollars cheaper than I have found elsewhere.
I have the same problem other have had with removing the old filter.  It definitely does not just screw off as they indicate on the instructions.  My husband had to remove the entire thing and then use pliers to get the old filter off.
It works we as a filter though, which is why I rated it 4 stars.  It just needs tweaked to be a little more user friendly perhaps.  I am happy with the quality of my water after using these filters and would recommend this to others.

This replacement filter fits our Kenmore refrigerator just like it said it would at about 1/3 of the cost of the one Kenmore recommends.  We installed this filter after being alerted by our fridge that one was due.  We let it go awhile past the notice and one day the ice and water wouldn't work.  We purchased this filter from Amazon and hoped it would be compatible (and it is).  Once installed, though, our water/ice still wouldn't work.  My husband does plumbing and after a little homework, decided we needed a new water inlet valve.  We ordered the valve from Sears since reviews of one on Amazon indicated limited success with installing an "off brand".  After the new inlet valve was installed, all works very well.  The filter does great.  We will order from WaterWater again when the time comes for a new filter.

These are great replacement filters and more than half the price of what i used to pay at a local store!

Great replacement filters. Knocked off 1 star because they are only charcoal filters and do not remove lead and other chemicals like the more expensive original filters. Not 100% sure of the numbers - but these are 42 compliant where the original is 42 & 53 compliant. (Those numbers may not be correct - but not taking the time writing this to go check.)

I think they are made in China... another ding. But, they fit, they remove odors and any bad taste .... and are much cheaper than original 42 & 53 compliant filters.

Please note: the filter fits into the winix machine out of the box, DO NOT USE with the plastic case if you plan to use this filter

--- Original Review ---
I bought this to replace a filter for the winix 9500 I own because we all know how their replacement filters cost $80 or more. This is GREAT & CHEAP alternative to winix's expensive filters.

For winix owners: this AP-300PH replaces this filter case: Winix 119110 Ultimate Replacement Filter

Installing these are a bit difference as you don't need the case that was included with your winix. They just slide in and fit tightly in on their own without a case.

Even though they are cheap doesn't mean the quality is less than that of an original winix filter. I found no difference in air quality when using this filter instead of winix's more expensive filter. Buy this!

Brand name replacement filter at a good price.

Good filter, worked just fine. But whatever you do, do NOT pay for installation. Who the hell pays $95 when all you have to do is pull off the passenger side drawer, slide out the old one, slide this one in, and then pop the drawer back in?

Do it yourself, save yourself $95 for a few minutes of work if even that.

I use my water through the fridge every day so when you think about spending $30-$40 on a replacement filter, at first glance feels like a lot of money - and it is. But, I've had this fridge for over 3 years and I've only had to replace the filter twice. Keep in mind that I'm waiting for the fridge to notify me to change the filter so maybe this should have been done long before but spending $30-$40 every 1.5 years doesn't seem so bad.
