How to Pick an Alkaline Water Filter? 

Buying an alkaline filter can be quite a tedious task, especially, if you are buying one of the large, bulky sets that have all-in-one functions and are expensive. So, here are a few pointers that will help you select the best filter for your purpose.               

Filter Type: This is at the core of your filtration setup. It powers the entire machine and decides the quality of water that you drink. While some alkaline filters are single filter systems, others contain dual filters.

Single filter systems are employed when the tap water source is known to be clean. If that is not the case, it is best to opt for the dual filter system that ensures the complete removal of all contaminants.

pH Range: The most important aspect of alkaline water is its pH. If the pH of your tap water is not right, the purpose of having such a device is thwarted. Therefore, always ensure that the pH of the filtration system is between 4 and 11.

Maintenance: The alkaline water filtration system is an investment. Once bought and installed, you want to use it forever. It is, therefore, important that its accessories or replacement filters are affordable to keep it in a perfectly working condition.

Lifestyle and Household: With several kinds of filters available in the market, making a choice can be quite difficult. But a deeper thought on your lifestyle, number of users, and budgetary constraints, if any, will give you a clear picture of the filer that suits your needs.

For instance, if you travel a lot, the alkaline filter water bottle is perfect for you. Whereas, if you need a device for family use, an RO or countertop model serves the purpose better.

Reviews and Testimonials: Read some unbiased and genuine reviews of users of the device to get a better understanding of its pros and cons.

Apec RO-PH90 – Best Alkaline Water Filter

Alkaline water filters aren’t exactly household items that you can just pick up whenever you feel like doing so. They are somewhat pricey, which is why it’s important to get a filtration system that you know will be able to last for a long time.

That’s the case with the Ultimate RO-PH90 from APEC Water Systems.

Remove Contaminants: The Ultimate RO-PH90 filter system is made from high-quality metal, allowing it to remain in great condition even after many years of usage. The faucet has been specially designed to ward off harmful contaminants such as lead.

Speaking of lead, this filter will get rid of that along with chlorine, fluoride, and other heavy metals that may be in the water supply.

Multi-stage Filters: To start, this filter works on eliminating larger particles that may be in the water with the help of the sediment filter. The extruded carbon block filter then works on eliminating odors and that is followed up by the reverse osmosis membrane that focuses on the contaminants such as chlorine and lead.

Natural Remineralization: The process ends with the remineralization filter which naturally adds in minerals such as calcium carbonate that raised pH of the clean drinking water.

Affordable Replacement Filter: The manufacturers made it a point to include high-capacity filters together with this filtration system. You can expect the originally installed filters to remain functional for up to a year. Replacement filters cost around $45 and they too will last for 12 months.

High Flow Rate: This filter is able to produce 90 gallons of filtered water per day with 4 gallons storage tank. It comes with 2 years warranty.

+ Highly durable water filtration system.
+ Filters usually last for a year.
+ High flow rate of 90 gallons.
+ Remove most contaminants with reverse osmosis membrane.
Produce wastewater as it happens on reverse osmosis filter.

pH Restore – Best Alkaline Water Pitcher

Filtration systems don’t necessarily have to focus solely on removing harmful contaminants in the water. As the pH Restore Alkaline Water Pitcher from Invigorated Water proves, your filtration system can also be a source of minerals such as calcium and selenium.

Filter City Contaminants: To be clear though, this filter pitcher also takes the job of eliminating contaminants very seriously. Examples of contaminants it can remove from your water supply include chlorine, chloramine, and lead among many others.

Multi-stage Filters: This filter pitcher utilizes a multi-stage approach to make your water healthier. The activated charcoal filter and micro-nets included in this pitcher target particles big and small to produce a cleaner, healthier, and more palatable type of water.

LIfespan and Cost: You can always purchase a 3-pack of replacement filter cartridges to ensure that you have clean water for up to nine months, but the bundle costs more than the filter pitcher itself. If it helps, you can think of it as each replacement filter that lasts for two months only costs around $17.

Expect to pay around $100 for a year’s supply of replacement filters.

The pricing would seemingly indicate that this is a vastly inferior product, but the water pitcher itself is quite durable.

If there is a downside to primarily using this water pitcher as your means of acquiring water, it’s that it doesn’t last very long. Each individual filter only remains serviceable for about two to three months.

+ Adds helpful minerals such as calcium and selenium to your water.
+ Does not take up a lot of space.
+ Portable and easy to bring around.
+ No installation is required..
Each individual filter is only expected to last for two to three months.
Maintenance cost is high.
