Whole house water filters, compared on published prices
A whole house water filter treats every drop entering the home at the main line: chlorine taste and smell, sediment, and with the right media a list of specific contaminants. It is a different tool from a softener, which removes hardness minerals, and different again from an under-sink unit that polishes one tap. The table below shows what the brands in this index advertise for their named whole-house systems, each figure verified verbatim against the brand's own page.

How to choose one that fits your water
- Start from a water test, not a symptom. Chlorine smell, sediment and staining have different fixes. A test tells you which media the filter needs: carbon for chlorine and taste, sediment stages for grit, and specialised media where a specific contaminant shows up.
- Match the flow rate to the house. Whole-house systems are rated in gallons per minute. Undersize one and showers drop pressure when the dishwasher runs; brands publish flow ratings on the same product pages this index links, so check them against your household's peak use.
- Count the replacement schedule, not just the tank. Tank-based carbon systems run years between media changes; cartridge systems trade a lower entry price for filter changes measured in months. The cost that matters is the system plus a decade of its consumables.
- Decide what pairs with it. Hard water still needs a softener or conditioner, and drinking-water polishing still favors an under-sink or reverse osmosis stage. Brands sell these as combos on the pages linked in the table; the combined price is often better than two separate purchases.
Filter, softener, or both
The commonest confusion in this market is between filtering and softening. A whole house water filter removes chlorine, sediment and specific contaminants, and does nothing about hardness; a softener removes calcium and magnesium, and does nothing about chlorine or contaminants. Homes on treated city water with scale on the fixtures usually want both, which is why the brands in the table sell filter-plus-softener combinations on their own pages.
The verified prices above are for each brand's named whole-house filter systems. Read the linked product page before buying: capacity ratings, what the media is certified to reduce, and whether a sediment pre-filter is included are all printed there, and they differ more between brands than the headline prices do.
Common questions
- Does a whole house filter soften water?
- No. Filtration and softening are different processes; hardness minerals pass straight through carbon. If you have scale, you want a softener or conditioner as well, and most brands in the index sell the pair as a combo.
- What do whole house systems cost?
- The brands in the index that publish prices advertise their named whole-house systems at the figures in the table above, each verified on the date shown. Cartridge-based systems start lower but carry ongoing filter costs; tank systems cost more up front and run years between media changes.
- Will a whole house filter fix well water problems?
- Not by itself. Well water with iron, sulfur smell or bacteria needs well-specific treatment ahead of, or instead of, a standard carbon system; see our well water filtration guide for how those systems differ.
