Water filters are becoming increasingly popular, given their ability to improve the quality of water in your home. But when it comes to choosing the right whole house filter type for you, one key question is whether you need a single-stage or whole house water filtration system. While both can provide benefits, a whole house water filter offers significantly more coverage and protection than its single-stage counterpart.
In this blog post, we’ll explore what a whole house water filter is, how it works and why it might be right for you.

Key Takeaway
  • A whole house water filter is a system that filters water coming into your home from the main water supply.
  • It works by passing all of the water through one or more stages of filtration, including sediment filters and carbon media to remove particles or chemicals.
  • Whole house water filters provide comprehensive coverage that extends to all points of use in the home, ensuring pure, clean water for your entire family.

What is a Whole House Water Filter?

A whole house water filter is an effective and efficient way to protect your family from contaminants in your water supply. It fits onto the main water line of your home, removing impurities such as chlorine, fluorine, and other chemicals that can be unhealthy for you and your family.

The system works by utilizing a series of filters designed to remove sediment, rust, pesticides, and other microorganisms from the water before it enters your home. These systems provide a superior level of protection against the numerous issues that may arise from drinking tap water. Plus they offer complete peace of mind knowing that the water you are consuming and showering in is safe and healthy for your entire family!

Different Types Of Whole Water Filtration Systems:

If you need a filter, there are various types of whole house water filtration systems to consider:

Sediment Filters

Whole house sediment filters are highly useful for anyone who wants to reduce their exposure to contaminants that can exist in tap water. They are designed to remove sediments, dirt, sand, and rust particles from the water coming into your home. The use of whole house sediment filters can definitely have a positive impact on the quality of your drinking water.

How Do They Work?

The working principle behind most whole house sediment filters is relatively simple: as pressure forces the water through a medium such as activated carbon or mesh fibers, debris becomes trapped in the medium, and clean water flows out of the other side. It’s important to understand that, while this type of filter removes particulate impurities only, it cannot reduce chemical contamination or eliminate bacteria and viruses. That said, if you want cleaner water without spending a lot to install an additional filtration system, a whole house sediment filter may be an economical option worth considering.

Carbon Filters

Whole house carbon filters are a great way to keep your home’s air clean and fresh. These filters help remove contaminants from the air, such as dust, pollen, viruses, and gases. The filter is usually made of activated carbon, a porous material that can absorb impurities as air passes through it. The filter is then housed in an appropriate holder which may contain one or more different kinds of carbon filters.

In addition to these benefits, these filters also aid in reducing allergic reactions in individuals who are sensitive to environmental allergens like dust and pollen. To maintain its effectiveness over time, it should be replaced regularly so that new activated carbon particles become available for capturing additional airborne impurities.

How Do They Work?

Carbon filters work by passing water through activated carbon which is dense and has a high surface area, making it absorbent and effective in trapping contaminants that can be found in drinking water. They help to remove chlorine and sediments, improve taste and smell, reduce particulates and optimize overall water quality.

The system provides clean, fresh-smelling water throughout the entire home without having to resort to costly bottled water options or other methods that can be inconvenient. With a whole house carbon filter, you’ll have peace of mind knowing that all of your drinking, showering, and cooking needs are taken care of with crystal clear, contaminant-free H2O!

Reverse Osmosis Systems

Reverse Osmosis (RO) is a top whole house water filter. It is an amazing solution to provide safe, clean water throughout an entire home. Unlike other filtering systems, these systems filter out a wider variety of contaminants, making them ideal for households in areas with greater contamination or uncertain sources of water such as those that get their water from wells.

How Do They Work?

Reverse osmosis systems slowly treat the water as it passes through a semi-permeable membrane where bacteria, salt, and other contaminants are safely removed while minerals essential to health are left behind. From there, the filtered water passes through several purification cartridges that remove things like chlorine and lead. The result is better-tasting and healthier drinking water directly from your tap! Plus you have peace of mind knowing the whole house has clean drinking water for everyone in your family.

UV Filter Systems

Whole house UV water filter systems are designed to clean water coming into a home from the main municipal line. This helps to ensure that all the water being used in your home for drinking, cooking, and cleaning is free from contaminants and safe for use. The system uses ultraviolet light to target and eliminate bacteria or microorganisms as the water passes through it on its way into your home.

While this type of filtering will not be able to eliminate all potentially harmful substances, it has been proven to be effective in diminishing bacteria levels significantly. Additionally, since it does not require any type of chemicals or maintenance other than periodic replacement of the UV bulb which typically lasts anywhere between one and two years, it is an economical choice for those looking to protect their family from contaminated tap water.

How Do They Work?

These systems work by using ultraviolet light to target and kill off microorganisms, such as protozoa, bacteria, and viruses, that can be found in the water. In order for this process to be effective, it is important that the light has time to interact and attach itself with the DNA or protein of each microorganism.

That is why most units include a stainless steel chamber within their construction. This chamber works as a storage tank for the water during treatment, so that the UV light can remain in contact with it for an extended period of time.

Depending on their usage, these systems will typically require bulb replacements every 6-12 months in order for them to remain effective. Investing in one of these filtration systems offers peace of mind when it comes to ensuring your family has clean and safe drinking water each day!

Whole House Water Filters Vs Countertop Filters:

When it comes to making sure you and your family have clean, safe, and delicious water for drinking and other purposes, there are a few options to choose from.

Countertop Filters

While countertop or under-sink filters are great choices for smaller households that don’t use much-filtered water throughout their day-to-day activities, they may not work as well in bigger households with higher water usage needs.

Whole House Water Filters

Whole house water filters offer an excellent choice in these circumstances — they filter all the water coming into your home at the point of entry, meaning every tap in your house has access to clean, filtered water.

Not only that, but these systems also require far less maintenance than countertop or under-sink models as they last longer and need fewer system replacements over time.

If you’re looking to filter all incoming water into your home and make sure everyone in your household has access to safe and delicious drinking or cooking water, then a whole house filter might be exactly what you need!
