Factors to Consider when Buying the Best Water Filter

The quality of your water supply will suggest how many stages of purification would go in the process so that you can get the best clean water to drink and cook in your home. Therefore, for better-tasting water, consider buying a water filter that suits your needs.

1. Water Quality

The water supplied to your home is hard water, which means your home water has a high TDS amount. Total dissolved solids in water contain inorganic salts such as calcium, magnesium, potassium, sodium, bicarbonates, chlorides, and sulfates. The best water filter to get rid of these inorganic compounds is a reverse-osmosis system.

This system’s membrane pore size is .0005 micron, making it impossible for the dissolved solids to exist in your drinking water.

2. Contamination

Due to the increase of factories and city infrastructure growth, metals are now found in water. Contaminated water contains heavy metals such as arsenic, magnesium, copper, and iron, and they can be toxic if taken in large amounts.

In reverse osmosis, the dissolved and suspended impurities get reduced; hence, it is advisable to choose an RO system. There are also some RO systems with mineral cartridges for areas with high TDS content.

3. Water Pressure 

Incoming water supply flow determines which filter you should get. A reverse osmosis system would work best with high water pressure. Water pressure is dependent on the elevation of your building and other factors like blocked pipes and clogged filters.

Water filters generally need a pressure of 5-40 pounds per square inch (PSI). A booster pump can also be attached to an RO system if the water supply in your home has less water pressure. Otherwise, you could go for an activated carbon purifier if your water supply has less TDS.

4. Electric Energy 

Many water filters do not work without electricity, and they are useful for homes with bad power shortages. An RO system would not work without electricity as it uses electric power to provide enough water pressure for the RO membrane.

Activated carbon purifiers don’t require electricity, just like sediment filters and ultra-filters. While the RO system removes TDS and bacteria that cause water-borne diseases, the non-electric water filters can only eliminate some of the chemicals dissolved in water, along with germs and sand. It is advisable to opt for water purifiers that run on electricity.

Frequently Asked Questions

1. How do I get filtered water in my apartment?

Being a renter should not force you to drink contaminated water. Therefore, consider buying countertop water filters or faucet fitting filters.

2. Which water filter removes the most contaminants?

Reverse osmosis filter systems are some of the most robust, most effective filters for drinking water. They are known to remove more than 99% of the most dangerous contaminants in the water. That includes heavy metals, herbicides, pesticides, chlorine, and other chemicals.

3. Why is Berkey banned in California?

It is permitted to sell outdoor Berkey Water Filter Systems to CA (Berkey Light and Travel Berkey). However, the other stainless systems cannot be shipped to California because they are listed as indoor filtration systems. California has other regulations that still affect some of the products.

4. Is Pur or Brita better?

The PUR filter removes more contaminants compared to the Brita filter. However, during a taste test and TDS tests, Brita performed notably better. If you have a more comprehensive range of contaminants you need to remove, PUR is the better choice, but for most consumers, Brita is better.

5. Is it okay to filter out water or drinks while traveling?

The Lifestraw water filter bottle, is suitable since it will work well with water only. It removes 99.9999% of waterborne bacteria and 99.9% of waterborne protozoan parasites.

6. Can the Lifestraw filter be hooked into a hydration bladder?

The LifeStraw filter does not have the right connections to hook inline into a hydration bladder. The LifeStraw Flex filter will fit inline in a hydration bladder.

7. How easy is it to clean the Berkey filter system, and how frequently does it need to be cleaned?

When the water compartment is empty, I unscrew the cartridge and rinse it off really well with plain water. I know it needs to be cleaned when the water starts coming out slower.

8. What is the difference between the older and newer version of the Soma pitcher, and can you use the same filter?

The pitcher and carafe use the same filter. There is an older and newer filter type, and both fit the carafe or pitcher! Soma is great on interchangeability.

9. How much do the replacement filters?

Filter cost is a thing to consider. A water filtration system is only as good as its filters, so be sure to factor them in, including price, availability, and how often they need to be replaced when deciding on your filtration system.
