Buyer’s Guide: How to Choose the Best Whole House Water Filter
It’s not simple to scour the internet for the most up-to-date information when you’re attempting to settle on the greatest product for your requirements. That is why we performed all of the difficult lifting.
This thorough shopping guide was created to provide you with information on everything you need to know to make an educated selection on the finest whole house water filter for your unique requirements. So, should we get started?
Water Consumption and Filter Capacity
A filter’s capacity is the amount of filtered water it can supply per hour (in gallons). As a result, the higher it is, the better the effectiveness of a filtering system. And the sooner you can get the advantages of drinking filtered water, the better.
Generic whole-house water filters, such as carbon-based analogues, do not waste water. Also, they have enhanced overall filtration capabilities. Since this water filter filtering technology does not flush any water away throughout the process, the water that passes through the filters is used around your house.
The capacity of a filter is determined by its quality in conjunction with the filter’s composition. While shopping for a product, check for the filtered water production rate in the specifications.
Type of Filter
As previously said, whole home water filters are classified into three types: next-generation technology, carbon-based, and reverse osmosis. Knowledge, as they say, is power. Hence, it’s important studying about the many filter types and the plethora of impurities they remove in order to choose the best suit for your home’s water quality.
Get a water quality report from your local water supplier if you haven’t already. The report includes a breakdown of the main constituents found in your drinking water. Compare these to the amount of pollutants in the nation.
Instead, you may test the quality of your home’s water using a water testing kit. They may be purchased online or at your local convenience shop. It will provide you with a clear indicator of the greatest amount of pollutants in your water. Once you know what’s in your water, you’ll know what kind of filter to get to remove these toxins.
The lifetime of a filter is generally determined by the product’s model, quality, and manufacturer. Whole home water filters have varying lifespans depending on their composition and the impurities they are supposed to remove. Pre-sediment equivalents often have the lowest lifetime since they rapidly get clogged with bigger particles, preventing them from adequately filtering water in the long term.
As a result, these filters will need to be replaced every 3 to 6 months. Re-mineralization and carbon filters, on the other hand, typically have a lifespan of 6 to 12 months. A reverse osmosis membrane has the longest lifetime, lasting up to two years before needing to be replaced.
Finally, it comes down to doing your research on a product to determine when its filters need to be replaced. Some whole-house water filtration systems feature a greater number of filters than others.
As a result, when it comes to updating them, you’ll need to account for this. Remember that no filter is indestructible. Hence, whichever model you choose, be prepared to replace your filters on a regular basis if you want to get the most out of them.
Available Space and System Physical Size
Physical installation of your home’s water system is required. As a result, you’ll need to make room for it to be installed. Also, you will need to connect the device to your home’s main water connection.
Not only will you need enough space to store your whole home water filter, but you’ll also want fast and simple access to the system when maintenance or filter replacement is necessary.
One micron is one millionth of a meter in length as a measurement unit. Since microns are so tiny, anything less than 40 microns cannot be seen with the human eye. To put things in perspective, a single white blood cell is around 25 microns in size.
Bearing this in mind, a water filter’s micron rating represents its capacity to remove impurities based on their micron size. A filter with a grade of 5, for example, has an incredible ability to detect particles as tiny as 5 microns. Nevertheless, keep in mind that this does not involve the efficient removal of these microns. This is why you should understand the distinction between absolute and nominal micron rating.
1) Nominal: It assesses a water filter’s capacity to remove certain particle sizes at a rate ranging from 50% to 90%. As a result, filters with a nominal micron rating of 5 may readily remove particles as fine as 5 microns with a 50% to 90% effectiveness.
2) Absolute: It describes a filter’s capacity to eliminate certain particle sizes with a minimum efficiency of 98.7%. Hence, if a whole-house water filter has an absolute micron rating of 5, it is more effective at eliminating particles with a diameter of 5 microns. It will remove at least 98.7% of the particulates in the water.
The micron rating of a product may be found in its specifications. Considering that particle sizes vary, a filter’s micron rating will reveal the sorts of particles that it can remove to the best of its capacity. A home water filtration system with a bigger kind of filter is typically the best choice for removing the most pollutants. Its filter is designed to remove various micron-sized particles.
There is a significant price difference between next-generation technologies, reverse osmosis, and carbon filters. The next-generation and reverse osmosis competitors cost hundreds of dollars, ranging from $1000 to $3000. Typical whole-house carbon-based filters are less expensive, costing between $300 and $600.
Yet, there are more expensive alternatives with additional functions like as UV filters or re-mineralization filters. Whole-house RO filters are the most expensive, with some costing more than $5000.
As compared to carbon-based alternatives, a reverse osmosis system is a far higher expenditure. Therefore, with a more flexible budget, you may determine if it’s worth it to spend the extra money to get the additional benefits that a RO filter brings.
Water Flow and Pressure
Your home’s water pressure is an important consideration since it directly affects the efficacy of your whole-house water filter, particularly a reverse osmosis system. You may believe that increased water flow or pressure is always the best option, but this is not always the case.
What you may not realize is that carbon-based filters function better with slower water flow since it allows the filters to remove particulates from water more completely over time. In contrast, 60 PSI water pressure is optimal for effective filtering with reverse osmosis filters. It allows water to reach the filters quickly enough to ensure the overall effectiveness of the operation.
This form of filtration needs enough water pressure to drive water through the RO at a suitable pace. You may test your home’s water pressure in PSI with a pressure gauge (available online or at your local hardware shop).
The finest whole home water filter is certified by NSF International or the WQA. The genuine certification certifies that the filter performs according to the manufacturer’s specifications. It also ensures that a filter is worth every penny.
1) National Sanitation Foundation International
NSF International, being one of the most reputable certification agencies, informs consumers that an independent third party has extensively assessed a product’s production process and decided that it complies to the specified quality, performance, or sustainability, and safety criteria.
2) Association for Water Quality (WQA)
The WQA, as an independent authority, assists consumers in determining whether a water filter and other quality improvement goods reach a predetermined high degree of knowledge and requirements. Manufacturers may get genuine certification from this agency as proof to buyers that their items have been certified by a third party for legitimate purposes.
Below are detailed answers to some of the most frequently asked questions.
What Exactly Is A Whole Home Water Filter?
A whole home water filter, as a point-of-entry water filtration device, provides crisp, clean, filtered water for a complete household and its appliances. Its attached to your main water line, therefore letting you to enjoy in filtered water throughout your house. The best whole home water filters include three or four filtering stages, as mentioned below.
- A pre-sediment filter eliminates bigger particles of sand, dirt, rust, and dust from the water. It keeps the latter stage filters from being damaged by these sediments, which reduces their lifetime.
- A zinc or copper combination filter is a beast when it comes to removing impurities like lead, mercury, other dissolved metals, and chemicals like chlorine, which have a detrimental influence on the odor and taste of water.
- An activated carbon filter is designed to cover the most surface area feasible in order to capture a variety of impurities such as organic compounds in its pores, allowing only tiny water particles to pass through.
- A post-filter that polishes the water one final time before it enters your home’s plumbing. As a result, it removes any silt that may have gotten past the prior filters.
If your home has many water heaters, you will only need one whole house water filter. You may benefit from filtered water if you put it on your water pipe that connects to all of your heaters. Whole home filtration systems, like basic kitchen sink water filters, come in a wide range of types, each providing a specific function.
2. What Are the Many Kinds of Whole Home Water Filters?
The following are some of the most well-known varieties of whole-house filters that achieve comprehensive water purification.
The process of reverse osmosis
It’s worth noting that these whole-house water filtration systems are much more expensive than other options. They also have higher maintenance expenditures. However, they provide unequalled effectiveness in the removal of the broadest variety of impurities found in water.
Although standard carbon-based filters cost hundreds of dollars, reverse osmosis filters for a single house may cost up to $6000, depending on the model’s sophistication. Keep in mind that this sort of whole home water filter does not save water since the RO process wastes around 4 gallons each gallon of filtered water.
Technology of the Future
Next-generation technology equivalents, another prevalent form of whole home water filter, have the ability to extract dissolved solids and pollutants at the same level as reverse osmosis filters. This sort of filter not only saves money but also does not waste water throughout the filtering process.
Additionally, next-generation technology water filters are a more environmentally friendly alternative to reverse osmosis systems. But, keep in mind that they are far more expensive than the carbon-based alternatives. Hence, for good next-generation filters, you may expect to spend about $2000.
3. Do You Need A Whole Home Filtration System?

Is a 5 or 50 micron filter better?
Larger particles may pass through a 50 micron rated filter than a 5 micron rated filter. Micron ratings for filters are typically 100, 75, 50, 25, 10, 5, 1, and 0.5.
Which is better 2 micron or 30-micron?
Racor advises using a 2-micron filter only in final or secondary filters after a primary filter has filtered the gasoline. Moreover, the business recommends using a 30-micron filter as a primary filter to filter raw or low-quality gasoline before passing it through finer media, such as a 10- or 2-micron filter.
Which is better 10 micron or 30-micron?
Larger particles may pass through the system using filters with a higher micron rating. A 10-micron filter is often used for unleaded gasoline, while a 30-micron filter is typically used for diesel fuel. Unwanted particles may slip past a 30-micron filter in an unleaded dispenser unit and into the customer’s car.
What type of filter water is healthiest?
Activated carbon filters organic compounds, chlorine, and most parasites from water, but a reverse osmosis system is most effective at removing heavy metals from water and can filter other contaminants such as nitrates and sulfates, according to Kylie Ivanir, MS, RD, registered dietitian of Within Nutrition.
