Not every Indian is fortunate to have access to municipality-treated water resources.

A significant majority of people depend on groundwater or river water for their daily needs. Now, a person who has used these sources will know that groundwater is hard and contains a lot of salt.

It explains why most of the people have RO water purifiers in their homes. This hard water has other undesirable effects.

  • It causes stubborn brown or whitish stains on the bathroom floors and walls.
  • The hard water causes undesirable deposits of salt on the sides of your utensils, plastic buckets, mugs, and bathtubs.
  • The salt deposits also choke the taps by accumulating at the nozzles thereby reducing the flow of water over a period.
  • The salt deposits stick to your electrical equipment like water heater coils thereby reducing their efficiency.
  • Hard water does not form enough lather with soap thereby affecting the washing of your clothes.
  • Hard water causes excessive drying of the skin by sticking to it and causing your hair to turn coarse and rough leading to hair fall.

What is the solution to these problems?

The perfect way to resolve this issue is to install a device known as a hard water softener to your taps. It is a kind of a filter for your taps and showers. It enables you to get soft water at the turn of a tap. We shall look into the mechanism of the hard water softener when we discuss the buying guide.

In the meanwhile, here are the best hard water softeners (filter arrangements for your taps and showers) available on the market.

We have seen five of the best hard water softeners available on the market. Each of these devices can help soften the water and thus rejuvenate the skin and hair. It also prevents accumulation of salts on the electrical devices like geyser coils, bathroom walls, bathtubs, and so on.

Let us now discuss the qualities that you should look for when buying a hard water softener (tap and shower filter). This buying guide should make your job easy.

Precaution – Note that the water softeners prevent the buildup of salt or other chemicals. They alter the harmful chemicals into harmless compounds. However, that does not make this water fit to drink. You should have a high-quality RO water purifier at home to purify your drinking water.

Buying Guide – Hard water Softener (Filter for tap and Shower)

Does your skin feel sticky after you take a bath? Does your scalp feel itchy every time you take a shower?

Do you notice a reduction in the water pressure after a couple of months of installing a new tap or shower? Are there white deposits of salt on the bathroom floors, walls, and electrical appliances like your geyser coils?

Do you see your bathtubs paling in color over a period?

If the response to all these questions is in the affirmative, you have a supply of hard water in your house. The ideal solution to these issues is to buy and install a hard water softener.

Usually, these softeners are available as filter arrangements that you fit onto your taps and showers.

Let us now discuss the benefits of using these hard water softeners in the form of shower and tap filters.

Reduces Chlorine – Chlorinated water is a disinfectant, but it can have disastrous effects on your body as the chemicals enter into the bloodstream through the skin when you take a shower. Chlorine also reacts with water to form dangerous compounds like chloroform that are harmful to health.

Makes water softer – Have a look at your electrical appliances that have exposure to water for a long time. Your washing machine tubs, your geyser coils, dishwashers, and so on develop a white layer of salt that goes on to affect its functioning. The water softeners make your water soft thereby eliminating the deposits of salts on these appliances.

Improve the quality of water – Water collected from your tap directly could appear turbid because of the presence of TDS (Total Dissolved Salts) and other contaminants. The use of these softeners removes the visible impurities and gives a transparent appearance to the water.

Improves your skin and hair – Regular washing your hair with soft water can make it glow. At the same time, your scalp feels healthy, as there are no salt deposits to make it feel itchy. It also prevents eczema and psoriasis and makes your skin look healthy.

Removes bad odor – The presence of chemicals in water gives it an unpleasant smell. Chlorine is the primary culprit. The use of water softeners removes the unpleasant odor caused by chlorine and other harmful chemicals. These water softeners also prevent the formation of bacteria and algae on showerheads and taps.

Types of Tap or shower filters

There are two types of tap or shower filters. The first one is the tap or showerhead filters, and the other is the inline filter.

Tap or Showerhead filter

These filters not only resemble a showerhead or a tap but also act like one. You install these bulky products on top of the tap or showerhead. These hard water softeners do their job of reducing the hardness of water effectively and ensure there is no loss of water pressure.

Inline filters

You have to install these inline filters between the showerhead/tap and the water line. The advantage of such filters is that you do not have to change your existing faucets and showerheads.

Filtration technology in use

There are various kinds of filtration technologies in use. You have the sediment filters and the porous PP cotton filters that offer basic protection. Hence, you have multi-level filtration in almost all hard water softeners.

Multi-level filters

Apart from the sediment and porous filters, you have additional layers comprising of ceramic balls, Maifan stones, and mineralizers to eliminate different impurities. Hence, you have many layers, sometimes extending up to 15 layers to provide high-quality filtration.

Activated carbon filters

Activated carbon filters can purify water by removing toxic organic compounds and bad odors. You also have these activated carbon filters in water purifiers. The job they do is identical in both the products.

KDF Filters

KDF 55 filters are instrumental in removing heavy metal impurities like copper, chromium, lead, and mercury. You can use these tap and showerhead filters in combination with activated carbon filters and the multi-level filters. KDF 55 filters, made of copper and zinc, can eliminate bacteria and other contaminants from water.

Vitamin C Filters

The Vitamin C filters are handy for eliminating chlorine and chloramines from water. Using them in combination with the other filters gives you a tremendous advantage as you can see an immediate improvement to your skin and hair.

Cost Factor

The cost factor of the hard water softener is critical. You should also focus on the lifespan of the cartridge and the cost of the replacements.

Check out the pricing and easy availability of the cartridges, as these filters are useless without the cartridges.

Filtration Capacity

Check out the filtration capacity of the cartridges before you purchase them. The filtration capacity depends on the quality of water. Usually, these cartridges last for around six months depending on how you use them.

On average, these cartridges should soften about 20K to 40K liters of water before needing a replacement.

If you do not like to replace them frequently, you should invest more and go for a cartridge that lasts longer.

Do the hard water softeners reduce the levels of TDS?

No, the hard water softeners do not reduce TDS levels. These products work on the ion exchange principle where it replaces the calcium and magnesium ions and remove the hardness of water by altering its chemical properties.
