Buying Guide of Best Alkaline Water Filters

If you are planning to switch to an alkaline water filtration unit for your household, you would probably want the best for yourself. To avoid being scammed or forced into buying any filter that is falsely advertised or does not fit your requirements, you should put thought into what kind of purifier would be the best choice for you and your home. To do this you need to consider the following features in these filters.


The most important feature you’ll want to consider is the type of filter that is installed in the purifying device. There are devices in the market that place all their focus on the ionization process and none on filtration. You should consider buying an ionizer whose filtration capacity is also remarkable and fits your needs.


Another important feature you would want to consider the type of plates in your filter. If you buy an electrical device it would include plates that use the process of Electrolysis to ionize the water and increase its Alkalinity. You might consider the number and type of plates used in your water filter.

Number of Plates

Many of the purifiers available in the market use between 5 to 13 plates. The number of plates in a purifier will determine how much alkalinity is added to the water. The more the plates, the more alkaline and better-tasting the water. In addition to that, most people prefer a filter with 9 or higher plates.

Plate Material

The build material of plates determines their ionizing properties. You should consider buying yourself pure metal titanium or Platinium. You probably wouldn’t want to buy anything that is made of alloy. Pure titanium plates will give the best electrolysis and have a strong resistance against erosion while platinum plates are best for the speedy process of electrolysis.

The Surface Area of Plates:

Another important factor to consider is the size of these plates. The size is also directly related to the surface area. a large surface area is as important as the number of would be useless to buy a filtration unit that has 13 tiny plates. You should consider buying a filter with large plates.

PH Level

The PH of the water decides whether it is acidic or alkaline. The lower the PH the more acidic it is and vise versa. Water is considered alkaline when the PH is above 7. ORP stands for Oxygen Reduction Potential. A negative ORP is required to fight the toxic substances in your body. As a general guide, you would want to consider buying a filter with a higher Ph rating and a lower ORP rating.

Flow Rate

When water passes through various filters, as in the case of purifiers, its flow rate is decreased. different purifiers come with different flow rates and will depend on the size and types of ionizing plates. The flow rate in many devices can be enhanced by turning off the ionizer.


The ease of cleaning the filtration devices depends on whether the purifier works on electricity or not. An electrical filter will be more laborious to clean compared to the non-electrical one that requires minimal effort to clean. However, most of the devices manufactured in today’s time are self-cleaning.


Another factor to consider is the ease with which the alkaline filter can be installed. Most of these purifiers come with an easy-to-follow user manual. The under-sink type purifiers are generally easier to install and comes with detailed instructions. With over-the-counter types, a little more effort is required. But you should first consider the dimensions of your home including faucets, pipelines, and electrical supply before buying any filtration device.


With any device, the warranty is an important factor to consider. You can get up to five years warranty with most of the devices available in the market. Many of these devices also offer a lifetime warranty. The buyers should ensure that adequate replacement facilities are available for the filters and plates so these are readily available when you need to replace them.
