A smaller filter a smaller price but a bigger performance than other filters I have tried. Don't waste your money as this filter is just as good at half the price. I love this 3 speed filter and will be buying another one.

It works well, but the filters get dirty so fast. I'll be buying a filter free one next time

Luckily I have 2 vehicles that use this filter so buying one type makes life easier.  Installs just like a standard filter and seems to work just fine.  Any additional protection it offers is a plus.

i have pets and the filters get to be a mess after awhile so you have to change them often and this is a good deal to get.

Didn't really need to buy
I bought a KN filter and it came with one so in the ad says this is what most people buy at the bottom Read the ad to see if it already comes with it

Is a filter and it works...not much else I can say.  If only it was cheaper.

The order process from multipure is ridiculous. If you do want to buy a filter system, you can try other system, definitely not mukltipure.

When I changed out my old air filter, this was the exact same one that was in there before, down to the branding and everything. At this price, I don't see the harm in changing it twice a year.

Its awesome. I never knew there were 2 filters! My instruction book doesnt even mention replacing a second filter. Just to wash the hepa filter!

These filters together are essentially the same price as a single name brand filter.  They work just as well as the name brand filter and I had no issue installing them myself.  The only thing I should tell you is that the icons on the name brand filter are NOT present on these off brands but you should still easily be able to align the filter.

Its one of those things you are glad to have when you need it.  Its a foam filter and it fits, not a whole lot else to add...

Every new hvac installation should include the box that holds this filter.  It might cost an extra $500.00 but it will save the system from ever needing a $800.00 cleaning as well as the loss of efficiency.  Remember folks, for those who have this, it should be the only filter you have.  Don't put any other filters in anywhere else where those 1" filters might normally go.  You don't want to double filter.  The 1" filters only reduce air flow and kill your fan motor.

You will never buy another filter well any way, not for a long time! You don't have to go to the store and drop $15.00 or so to buy a filter! You have the filter there and all you need do is rinse it off once a month or so!

I really like this filter. It is easy to use. You can design and change the filter media as you choose. The nicest thing about the filter is that you can use standard filter media (poly-fiber, carbon, etc) and not have to purchase pre-manufactured filter pads/cartridges that most companies make you buy for their filters. I do think that the filter could be made with a more durable plastic. The plastic is very flimsy and thin. If you do not plan on handling the product much it might last for a while, but I seriously doubt it. Mine is already cracked and I just put it into my tank. The shipping costs more than the filter, so I recommend buying multiple filters at one time. I am sure that you will be replacing it regularly.

Just put this filter in. It fit perfectly and seems to work well, time will tell. This two pack replaces a single filter that I had bought before. A two pack for roughly $10 replaced a single filter for $50, so i very happy so far.

Previous filters offered only 6 months filtration versus Watts 5 year filtration.  Same installation process.  Sum result is that this is an easy job that now needs to be done less often.
