pH Adjustment for Drinking Water: Fixing Acidic and Corrosive Water pH Adjustment for Drinking Water: Fixing Acidic and Corrosive Water Who this is for: primarily well owners seeing blue-green staining on fixtures, pinhole leaks in copper pipes, or a metallic taste — the signature signs of acidic, corrosive water. Low pH water attacks plumbing, and…
Adsorptive Media: Activated Alumina, Iron-Based Media, and Specialty Adsorbents Adsorptive Media: Activated Alumina, Iron-Based Media, and Specialty Adsorbents Who this is for: people dealing with specific dissolved contaminants — arsenic, fluoride, or iron and manganese at levels where carbon alone is insufficient — where the right media is a specialty adsorbent rather than activated carbon….
Ultrafiltration (UF): Tighter Than MF, Looser Than RO Ultrafiltration (UF): Tighter Than MF, Looser Than RO Who this is for: people who need a biological barrier that reaches into the virus range — beyond what microfiltration can reliably claim. UF pores run 0.01 to 0.1 micron, which puts most viruses within reach and makes UF…
Microfiltration (MF): What It Removes and When You Need It Microfiltration (MF): What It Removes and When You Need It Who this is for: anyone dealing with biological contamination — bacteria, protozoa, cysts — who wants a membrane-based barrier rather than a cartridge filter. MF sits between a sediment filter and ultrafiltration on the size…
Nanofiltration: The Membrane Between Ultrafiltration and RO Who this is for: anyone weighing reverse osmosis who would rather not strip their water down to nothing. Nanofiltration is RO’s looser cousin — a membrane with slightly more open pores that takes out the heavy, multiply-charged stuff while letting some minerals through. That one difference is the…
Who this is for: anyone considering an under-sink RO system, anyone who has been told RO is the gold standard for drinking water and wants to know what that actually means, and anyone trying to decide whether they need one. RO is the most oversold residential water treatment technology there is. It is also genuinely…
Who this is for: anyone on a private well, surface water, or any source where bacteria, viruses, or protozoa are a concern. UV is also worth understanding for anyone building a multi-stage system — it is almost always the last active treatment stage before water reaches the tap, and knowing what it does and does…
Who this is for: anyone who wants thorough contaminant removal without a pressurized water supply, homesteaders and off-grid households who need treatment that works without plumbing, and anyone who has been told distillation removes everything and wants to know what that actually means — and what it misses. The Short Answer Distillation is the oldest…
Who this is for: well owners with iron, manganese, or hydrogen sulfide in their water — the rust stains, the black stains, and the rotten-egg smell. Caution, sometimes pink stains can be mistaken for iron but are caused by non-harmful pink slime bacteria. If you are on city water, this page is not for you….
Who this is for: anyone with hard water, elevated nitrate, PFAS concerns, or tannin-colored water. Ion exchange is one of the most targeted filtration mechanisms available — it trades one specific ion for another — which makes it very effective for the right problem and completely useless for the wrong one. If your concern is…
