Review on Ridgid VF4000 Standard Filter - White by Gary Shakeone

Works well but someone is making a lot of money. Compare that to your car's oil filter, which you can buy at Walmart for $3 to $5, and add some more paper, probably $0.05 to $0.10. This is a beater for all filters, including the filter you buy to "file" the water you put in your fridge. And they all make them different, so you need to buy them and buy a paper filter for your air conditioner. Think about it!
