Bought to save money and will never buy again! I usually buy one brand of my car that comes in a 2 pack for the same price as this 4 pack. I'm used to changing filters maybe every 1-3 months since my machine is running all the time. With these filters, I change them every 2 weeks or less. because they get wet very quickly leaving sludge out of the filter on the bottom of my car and the water no longer flows out to refill it like it should. I always buy distilled water, so instead of using the water I use paper towel filters. Do not buy!
