Cellulose or Pleated Poly filter for BigBlue ?

Greetings. We are on well water in rural Oregon. Water tested for bacteria 2-3 times a year. All good results for 10 years. No chlorination.

Have been using a 20 micron Cellulose 20 x 4-1/2 for years. Supply store advises Cellulose attracts mold....... and recommended a switch to Pleated Poly.

This filter usually changed out 2x a year and is first in line. Next comes a calcium pH adjuster tank....than an iron reducer tank....and next a water softener. A small, polishing 10 micron, string sediment filter is last in line

Any comments will be appreciated.

 

So there filters and then neut and iron reducer tank? then softener.
Why the pre filter is there sand?
As the waters ph is corrected some iron will fall out so neut should be backwashing about every 2 or 3 days.
What is the iron reducer tank???
And 10 micron post filter?
Really?

Has any one tried running with out pre or post filters for 6 months to see what happens?

 

I have 2 big blues which are pre filters (one for the house and one for the GEO furnace) removing insoluble iron and misc crud, sediment filters.

Pleated filters are similar to what is used in a spa.

I have never heard of mold being an issue with a functional filter.

Since these are used as pre-filters, I buy in bulk and change often, 4-6 times per year!

 

Did some research and find that the cellulose filter we have been using is prone to bacterial infestations and bio-film. Plus they will disintegrate if not replaced after 3 months. (I have noted this to some degree).

So I will switch to a pleated polyester or polypropylene.

Any advice as to which type.....?

 

Hello again....I sent away for a Harmsco WB-HB-20-20W.....pleated poly.

Thanks for all your suggestions.......
