Why Whole House Filters are Necessary for your House

Water plays a central role in our daily lives and with the increasing rate of pollution in the modern world it is plausible to be more practical about safeguarding our health and that of our loved ones by having a purified water system installed in the house. Whole house water filters or the point of entry(POE) filtrations are fitted in the main water line hence filtering all water-related contaminants before the water is distributed to the kitchen for cooking and drinking, to the bathroom for bathing and to the laundry section for cleaning. According to research, most chemicals and pollutants get into the ecosystem and are spread through common mediums such as water accounting for many diseases and infections directly and indirectly. Common pollutants found in water include nitrates, radon, arsenic, traces of drugs and even hormones. Chlorine used for disinfecting municipal water may also alter taste and is sometimes excessively used in the main supply. (Effective ways of removing chlorine from tap water)  This may be introduced to the body by drinking water and also through bath water as some chemicals will absorb directly into the bloodstream from getting in touch with contaminated water. Accruing yourself the appropriate water filter could save you money and consequential grief as the quality of water varies from one region to another.

Factors to Consider when Choosing the Best Whole House Water Filter

The most suitable whole house water filter has to be very efficient in eradicating contaminants from any given water source. Such is in regard to making water purer, giving it a pleasant taste and eliminating all odours. Below are important considerations to go through when narrowing down your list of choices for the perfect filter.

Nature of impurities in your water supply

Knowing the impurities to focus on will guide you to purchase a more specialized water filter. This can be achieved by reviewing annual water quality reports by your water supplier. Other options may involve testing the water personally with a home test kit which is readily available in most home improvement stores. If you are not lucky enough to get a kit you can always reach out to your water supplier to get connected to a local laboratory. Depending on the concentration of impurities you can buy a carbon, reverse osmosis or distillation filter. Carbon filters are designed for pour through systems to trap impurities with their high absorbing rate and positively charged filter. Reverse osmosis rewinds water flow into a semipermeable membrane and is not as common in the market because it greatly reduces water flow and leads to wastage of water. Distillation filters conduct heat to the water then collects the steam in a condensation process. There are pollutants that convert to steam with the water hence escaping the purification process but this can be remedied by purchasing a distillation water filter that is fitted with an additional carbon filter.

Review how much you are willing to spend on a filter

You will be presented with multiple options to choose from but a good filter will incorporate an active filter for carbon. This will take care of the heavy metals such as lead, copper and mercury as well as other elements such as pathogens, volatile organic compounds (learn more about VOC), pesticides and chlorine. The presence of impurities such as perchlorates will require an alternative purification mechanism that can facilitate reverse osmosis. Impurities like arsenic, on the other hand, will require a distillation system. Some whole house filters can be very pricey depending on their features but in the long run, they are worth the cost. This is because they eliminate the need to constantly buy bottled purified water for house utility which accumulates cost and also minimizes the chances of contracting infections and diseases. Other cost implications to consider is the rate at which the filters will need to be replaced as this will add the overall cost of maintenance.

Water flow rate

Before making a purchase, you must assess the overall consumption of water in your household per day. Water flow is usually rated in gallons per unit time for water running to the kitchen, shower, toilet, garden and so on. Different filters offer different flow rates hence you should be careful not to pick one that minimizes the water pressure in your house. The effectiveness of the filter is measured in microns. The lesser the micron rate for the filter the more contaminants get removed from the water supply. High micron rate indicates that debris such as sand, rust and silt gets blocked but finer contaminants such as lead, fluoride and pathogens pass through. You can choose a whole house water filter from the range of 1, 5, 10, 25, 50-micron rate. Reverse osmosis filter systems have the finest micron rating of up to 0.0001 but the downside is that they reduce the flow rate drastically making it trickle.

Size of the Filter

A bigger filter will increase the intervals of the purification process which means more water will flow hence a greater pressure. For normal size homes, the recommended filter size is 4.5” x 20”.

Size of the port

The most recommendable port size for most houses is 1”. For a 4.5” x 20” whole house water filter 1” port ensures adequate flow of water and sustains the water pressure without causing any pressure drops. Even for houses fitted with the ¾” pipes the 1” port still comes in handy without creating bottlenecks.

Filter replacement

For a whole house water filter, the main filtration media needs replacement after 5 to 10 years which all depends on the system you choose. For the pre-filters however, they have to be replaced in the intervals of 2 to three months while the post filters last between 6 to 12 months depending on the quality of the system.

The iSpring WGB22B is an effective yet affordable whole house water filter produced from a trusted brand.

This means that you can call anytime you are experiencing challenges with the model and a qualified technician will systematically guide you in resolving your query.

The second stage refines water from finer contaminants and unpleasant odours giving your water a pleasant taste.

The installation process should be fitted with a shutoff valve to avoid wastage of water and creation of a mess whenever you want to change the filters.
