First some background info: In my kitchen I have an under the counter 3 compartment Omni Water Filter housing, which I've had for over 10 years. I use 3 different kinds of filters. The first housing has a sediment filter which gets replaced every 3 months, the 2nd has a activated charcoal filter for more filtering, and the 3rd housing has an expensive carbon block filter that takes out anything and everything else. The 2nd and 3rd filter get replaced every 6 months. I also vigorously clean the inside of the housing every 6 months with bleach.
When my local Home Depot stopped carrying Omni replacement filters, I went with what they had, which was GE replacement water filters and Culligan water filters, that are made to fit in my filter housing. No problems with the replacements, but on specs alone, the Omni filters were supposed to be better. When my local Lowe's started carrying the Omnifilter brand, I went back to that brand of filter.
Lately, for the last year, the water has been tasting terrible, really terrible, and not the water that comes out of the tap, but the water that comes out of the filter. I replaced the filter faucet, the filter supply tubes, new filters, practically everything was replaced except the filter housing, and the water still tastes terrible. I removed the expensive carbon block filter today, and everyone agrees the water is much better, but this filter with it's under 1 micron size filters out whatever pesticides, lead, etc.. that most filters won't.
All that leads me to this:
Would you know if these filters are actually made by different companies, and just resold by Omni, GE, Culligan, etc.. OR is it likely that these are made by different companies and I can get a different water taste by trying someone else's filter?
I thought I remember the water tasting better with the GE filters, but it's been 2 years since I used those, and I could be wrong.
