I bought this product because of the price. It was difficult to tell. I greased the O-rings and screwed in 2 filters. It took several attempts to get it flowing. After 2 days, one of the two tubes begins to vibrate heavily and make a loud noise. I have removed and reinstalled them several times. The same tube vibrates strongly, making a loud noise everywhere. I tried each of the old tubes in place of the faulty ones and they didn't vibrate or make any noise. The filter is defective. As soon as you turn on the water, a new hose begins to vibrate. I'm sending them back. Pay more money and get GE filters.
