What is a Whole House Water Filter?

A whole house water filter gives you ready-to-drink water by removing toxins like heavy metals, excess chlorine, pesticides, herbicides, and sediments. You’ll install a whole house water filter at the main Point of Entry (POE) before the water reaches other fixtures, faucets, or appliances like water heaters.

How a Whole House Water Filter Functions

Different brands will have varying filtration techniques, but the common ones are reverse osmosis and UV treatment. Reverse osmosis technology is prevalent on carbon-based and KDF filter media. 

This filtration technique will eliminate sediments and prevalent contaminants like excess chlorine and heavy metals for cleaner, better-tasting water. On the other hand, the UV filtration technique will be best for removing microorganisms like viruses and bacteria.

Why Do You Need a Water Filter In Your Home?

Unless you’re drinking from bottled water, you’re running a risk of contracting waterborne diseases if you rely on untreated tap or well water. Remember, you don’t have control over the well water source or the piped municipal water treatment processes. Notable toxins that may bypass the treatment process at the municipal level include old pipes with leaks or sediment buildup. Well water may also be prone to organic contaminants like herbicides and pesticides.

A high-quality water filter removes these toxins to give you an endless supply of clean water. Better-tasting water improves your consumption patterns for general wellbeing. Remember, adequate clean drinking water means better skin and eye health.

Buying Guide for the Best Whole House Water Filter

Have the following considerations in mind before buying a whole house water filter:

Target of Filtration

As noted, different brands come with varying filtration media to remove specific contaminants. You’d want a system built specifically to deal with your water supply, whether it’s in the city or the countryside. Prevalent water contaminants emanate from the source and the plumbing system it travels through before reaching your home.

Your filtration targets can be:

1. Tap Water

It isn’t uncommon to come through excess contaminants in state-approved tap waters, whether you live in the suburbs or low-life neighborhoods. You might want to take a sample of your tap water to a local lab to discern the type of contaminants in your supply. Buy our best filter for tap water if you’re dealing with the following contaminants:

  • Carcinogenic Volatile Organic Compounds like benzene
  • Radioactive elements like radium and uranium
  • Heavy metals like lead, copper, and arsenic
  • Excess disinfectants like chlorine, fluoride, and chloramine
  • Disinfection by-products like chloroform

2. Well Water

Well water can either be from a private or communal source. If you have a private well, send a sample of the water to a local laboratory to determine the type of contaminants present. The most prevalent contaminant in well water is iron. 

Even though this metal doesn’t have a significant health effect, it causes an odd taste and smell in your drinking water. Buy our best filter for well water if you’re likely dealing with the following toxins:

  • Organic chemicals like herbicides and pesticides
  • Radionuclides like uranium
  • Clay and silt sediments
  • Heavy metals like copper, arsenic, and antimony
  • Microorganisms like viruses and bacteria

Factors to Consider Before Buying a Whole House Water Filter

Whole house water filters will serve you well if you consider specifications that match your expectations, budget, and water needs. Each product reviewed above is unique and will give an exemplary performance in various situations. Some also have a higher price tag because of the technological features that enhance ultra-filtration performance. Consider these factors when making a purchase, whether online or in physical stores:

1. Consumption and Filter Capacity

Your main consideration should be the consumption or filter capacity of a specific product. The maximum capacity should reflect your household’s consumption rate. Averagely, a single person uses up to 250,000 gallons of water every year. If your family has about four to five people, you’ll need to buy a whole house water filter with a maximum capacity of up to 1,000,000 gallons.

Some brands also have the capacity feature to represent the filter’s lifespan. Thus, the higher the capacity, the more you’ll enjoy the system’s longevity to see your money value. A small household of about one or two people can do well with a capacity of 500,000 gallons. Most of the above-reviewed products have a capacity of 1,000,000 gallons.

2. Types of Filters

What is the best filter? Besides micron rating, you’d want a high-quality filtration media that doesn’t allow contaminants to pass through. We discovered that coconut-based carbon filter media has the best reverse osmosis filtration technique to remove sediments and particle contaminants. It can also remove prevalent organic toxins like herbicides and pesticides.

On the other hand, KDF filtration media proved to be the best in enhancing taste by eliminating odor and excess chlorine concentration. It will help if you buy a whole house filter system with multiple filtration media for efficiency.

3. Filter Longevity/Lifespan

A filter media with a longer lifespan will save you money and resources associated with unnecessary replacements and maintenance schedules. However, kindly note that most manufacturers don’t give a specific lifespan. Instead, they’ll tell you when to consider a replacement, say after six to nine months or when you start experiencing fluctuating water flow rates.

Even so, the flow rate fluctuation can still be due to multiple users at a time. If you’re dealing with heavily polluted water, your filter media may not outlast the recommended manufacturer’s lifespan.

4. Size

The size of a whole house water filter system is purely aesthetic and will depend on individual preferences. Don’t confuse big size with efficiency or functionality. Similarly, don’t mistake a small size for defectiveness. Watch out for specifications because the size will only determine your installation point.

Manufacturers don’t design these whole house water filters for mobile operations, and size doesn’t matter unless you want to maximize space. Even so, a small-sized water filter will likely give you an easy time when installing compared to big models that may require professional plumbing.

5. Micron Rating

Micron rating will determine whether you’ll get the most out of your whole house filter. If a product filters your water in more than one stage, it will help if each stage features a different micron rating. Different filtration stages with the same micron rating don’t make any difference from a single-stage micron rating.

Watch out for products with a lower micron rating of about five or below. This rating guarantees the removal of nearly all contaminants, including silt, clay, and mineral sediments.

6. Water Flow/ Pressure

The water flow rate choice will depend on your household’s size. A bigger family will need a filter with a flow rate of at least 25 GPM. Even so, different faucets may still experience varying flow rates depending on the fixture’s size and the number of users at a time.

If the kitchen faucet is open together with the bathroom sink, you may experience relatively low flow rates of about two and three GPM, respectively. Smaller families of about two to four people will still have a good experience with smaller water filters of 10 GPM, or even lower.

7. Certifications

Certified water filters will give back your money’s value through longevity and durability. The most reputable certification to watch out for in whole house water filters is the NSL listing. However, it will help if you’re keen because some products will have certified components and not the product as a whole. 

Such water filters may not guarantee the quality of water coming out at different fixtures. Moreover, “NSF-listed” is quite an ambiguous term and may represent a specific contaminant. Here are the prevalent NSF certifications:

NSF Standard 58 – prevalent in products with reverse osmosis filtration technology. This certification guarantees Total Dissolved Solids (TDS), lead, copper, and arsenic filtration.

NSF Standard 55 – certification for Ultra Violet (UV) whole house water filters. It guarantees pathogenic bacteria, microorganisms, and virus filtration.

NSF Standard 53 – you’ll find this certification in water softener filters. It accredits health-related contaminants filtration like cyst and lead.

NSF Standard 44 – this certification guarantees hard mineral reduction. It is available in water filters capable of barium and radium 226/228 reduction.

NSF Standard 43 – this certification is for aesthetics reduction, mostly odor. It also guarantees chlorine reduction for better-tasting drinking water.

The Bottom Line

High-quality whole house water filters like those seen above will give you clean, instant drinking water for up to 12 months before replacing the filter. Most of them attract fewer maintenance costs, and you don’t need to worry after installation. Even so, don’t forget to double-check a product’s specifications and whether the certification is for the system as a whole.

The more the certifications, the more likely you’ll get the most out of your whole house water filter in efficiency and durability. You can buy these products from Amazon or official manufacturer websites.
