Chlorine taste, cloudy water, or scale can push any homeowner to consider a whole house filter. Before you buy, understand the real whole house water filter disadvantages so you do not waste money or pressure. At Summers Plumbing Heating & Cooling in Huntington, we install, repair, and maintain filtration every day, and we will help you choose the right setup without surprises.
What a Whole House Filter Can and Cannot Do
A whole house filter protects every tap, but not all problems. Most cartridge or media filters target sediment, chlorine, or specific chemicals. They do not soften hard water unless a softener is included. If your main issue is limescale on fixtures and appliances, a softener or a combined solution may be the better choice.
- What it usually handles:
- Sediment and rust
- Chlorine and related tastes or odors
- Certain chemicals depending on the media
- What it does not handle by itself:
- Hardness minerals that cause scale
- Microbes unless you add UV or equivalent disinfection
- Nitrates or dissolved solids without advanced media or RO
Fact to know: Reverse osmosis provides high-quality drinking water at a tap. It is rarely used as a whole house solution because of cost, space, and waste water. Our team often installs RO at the kitchen sink for cooking and drinking, then uses a softener or whole house media filter for the rest of the home.
Disadvantage 1: Pressure Drop and Flow Limitation
Any filter placed on the main line adds resistance. As filters load with sediment or chlorine, pressure drop increases. You may notice slower showers when multiple fixtures run. Undersized systems make this worse.
- How it shows up:
- Great pressure at one sink, but pressure falls when the washer or another shower is on
- Short filter life in homes with high sediment
- How to reduce the risk:
- Size the system for peak flow, not average use
- Use staged filtration where needed, such as a separate sediment prefilter
- Monitor pressure at service valves and replace media on schedule
Local insight: In many Huntington and rural Huntington County homes, well pumps can surge sediment after maintenance or heavy use. A dedicated sediment stage helps protect the main carbon filter from early clogging.
Disadvantage 2: Ongoing Maintenance and Filter Costs
Filters are consumables. Media tanks eventually exhaust and cartridges clog. Skipping service leads to pressure loss and water quality drift.
- Real numbers you should plan for:
- Reverse osmosis systems have three types of filters that need annual changes
- Many carbon cartridges need replacement every 6 to 12 months based on water quality and use
- Media tanks often last 3 to 5 years before a rebed, depending on chemistry and volume
- Why pro service helps:
- Correctly flushing and sanitizing housings keeps biofilm from forming
- A technician can test hardness and chlorine on the spot and right-size the maintenance schedule
We recommend scheduling tune-ups so you avoid untimely or costly repairs. Consistent maintenance keeps pressure and taste steady.
Disadvantage 3: Space, Bypass, and Access Constraints
Whole house systems need room near the main line. Tight basements and crawlspaces can force awkward installs that make service harder later. If there is no simple bypass, you could be without water during service.
- What to check before you buy:
- Clearance for tank height and cartridge changes
- Easy access to shutoff and bypass valves
- Drain availability if your setup includes backwash or RO waste
- Smart layout details:
- Mount housings at a height where a filter wrench can turn without hitting joists
- Label the bypass so any family member can restore water in seconds
Our trucks are stocked with unions, valves, and brackets so we can create clean service loops even in tight Huntington basements.
Disadvantage 4: Over-filtering Chlorine Can Invite Biofilm
Removing nearly all chlorine at the home’s entry can improve taste, but you also remove a disinfectant that controls bacterial growth inside plumbing. Warm, stagnant branches are most at risk.
- Situations to watch:
- Vacation homes or long unused bathroom lines
- Homes with large hot water recirculation loops that stay warm
- Practical precautions:
- Right-size carbon media to reduce, not strip, chlorine when appropriate
- Periodically flush little-used fixtures
- Sanitize housings during filter changes
A balanced approach often works best. Many families prefer full chlorine reduction at the kitchen and showers while keeping limited residual through select zones. We will explain tradeoffs before you decide.
Disadvantage 5: It Will Not Fix Hard Water by Itself
A whole house filter does not remove hardness minerals. If your fixtures spot and your dishwasher films, you likely need a softener.
- Common symptoms of hard water:
- Scale on glass, fixtures, and water heaters
- Dry skin and dull laundry
- Your options:
- Salt-based softeners remove hardness minerals and need salt refills
- Salt-free conditioners reduce scale on surfaces with less maintenance, but they do not actually soften water
Professional installation is recommended. Correct sizing and integration into your plumbing deliver best results from day one.
Disadvantage 6: Some Contaminants Need Specialty Media or RO
Standard carbon or sediment filters do not treat everything. If testing shows nitrates, arsenic, or very high total dissolved solids, you may need specialty media or a point-of-use RO for drinking and cooking.
- Good first steps:
- Get a water test for city or well water
- Match media to the exact issue rather than guessing
- Consider RO at the kitchen with a whole house system for broad coverage
Summers installs and services reverse osmosis for Huntington homes and businesses. We handle installation, filter changes, maintenance, repairs, and replacement.
Disadvantage 7: Upfront Cost and Hidden Add-ons
Prices range widely. Smaller cartridge systems cost less, but frequent replacements add up. Larger backwashing units cost more at install, need power and a drain, and may require a permit and backflow device.
- Cost drivers to consider:
- Water tests and proper sizing
- Shutoff and bypass valves, unions, and wall brackets
- Electrical and drain access if the unit backwashes
- Media replacement timelines and labor
- How we control budget surprises:
- Upfront pricing with options
- Price match guarantee against written competitor quotes
- Financing available on approved credit
Disadvantage 8: Installation Errors Can Create Leaks or Code Problems
Improper sweats or cross-threaded housings can weep under pressure. Incorrect placement ahead of the fire sprinkler riser or without a required backflow preventer can violate code.
- Avoid these mistakes:
- Unsupported piping that puts strain on housings
- No expansion tank on closed systems
- Using the wrong pipe dope or overtightening plastic threads
- What a pro does differently:
- Confirms local code, permit, and backflow requirements
- Pressure tests at working pressure before leaving
- Labels shutoffs and documents media schedule
Summers has provided service since 1969 with licensed, background-checked plumbers. We install to code and test before we leave.
Disadvantage 9: Taste Expectations May Not Match Reality
Many homeowners expect bottled-water taste at every tap. Whole house filters improve chlorine and odor, but dissolved solids and minerals still influence taste. Kitchen RO or a fridge filter may still be ideal for drinking.
- Set clear goals by outlet:
- Whole home: reduce chlorine and sediment, protect plumbing and skin
- Kitchen: use RO or a dedicated system for crisp taste
Disadvantage 10: Not All Systems Are Friendly to Every Appliance
Some appliances expect a small amount of chlorine. Fully dechlorinated water can allow biofilm in appliance hoses over time if not maintained. Also, softened water can void certain appliance warranties if hardness must be present for sealing surfaces.
- Practical approach:
- Follow the appliance manufacturer’s water spec
- Pair the right filter or softener, and schedule routine hose and inlet screen checks
When a Whole House Filter Still Makes Sense
Even with these drawbacks, a correctly designed system is valuable. If your priority is better tasting showers, protecting water heaters from sediment, and reducing chlorine exposure, a whole house filter can deliver. Pair it with a softener for hard water and add RO at the kitchen for premium taste.
- Best practice stack many Huntington families choose:
- Sediment prefilter to protect flow
- Carbon media for chlorine and odor
- Water softener for scale control if needed
- RO at the kitchen sink for drinking and cooking

Frequently Asked Questions
Will a whole house filter soften my water?
No. Standard whole house filters remove sediment and reduce chlorine. They do not remove hardness minerals. For scale control, add a water softener or a conditioner.
How much pressure drop should I expect?
A correctly sized system typically has a small pressure drop that grows as filters load. If you notice weak showers during peak use, it may be undersized or overdue for service.
Do I need reverse osmosis for the whole house?
Rarely. Whole home RO is costly and complex. Most homeowners use RO at the kitchen sink for drinking and cooking and use a softener or media filter for the rest.
How often will I change filters?
Carbon cartridges often last 6 to 12 months, depending on water and usage. Reverse osmosis has three filter types that should be changed annually for best performance.
Can removing chlorine increase bacteria in pipes?
It can in low-use branches. Chlorine controls growth. If you dechlorinate at entry, flush unused lines and sanitize housings during filter changes to reduce risk.
