These filters work fine. Be careful when it comes to filter changes.They are only effective for one year. If left in longer than one year,they will begin leaking. The end of the tube are clear. the u.v.light does effect the john guest fitting on the ends. It will leak after about 14to 16 months. Let it go 18 and you will be sorry.
