To choose the right water filter, the first thing is to know your water.

Here are two simple ways for your reference:

Take a cup of water, drip 2-3 drops of pH reagents and you can determine the pH while consulting the shade guide. And you will easily know the acid-base property of your home water.

Take a cup of water, drop in 2 to 3 drops of chlorine drip reagents; you can determine the content of residual chlorine with reference to the shade guide. pH reagents and chlorine reagent can easily be purchased in common chemicals shops or health care products companies.

Pick a full glass of water and make sure the glass is highly transparent; watch carefully whether there is fine matter suspended in the water. If the answer is yes, it means the level of suspended impurities in the water is far higher than the normal. And a water purifier is needed for terminal treatment.

Fill up your glass with water from a tap, and smell it, if it does have the smell of bleach (chlorine), it certainly indicates that the excessive chlorine existed in the tap water. And terminal treatment must be carried out by simply using a water filter.

Have a sip of boiled water, if you can taste the smell of blench (chlorine), it means the chlorine is beyond index and a water filter is certainly needed.

Make a cup of tea with home tap water, and watch whether it turns black after overnight. If it is, it means the water contains iron and manganese is seriously out of limit. Thus a water filter in view of the removal of iron and manganese is required for terminal handling.

Check out the wall of your water heater and kettle. If there is a layer of yellow scale, it means it is hard water. (i.e. high levels of calcium, magnesium, and salt). And a water softener could certainly solve the problem. Hard water deposits also clog pipes of water heaters and shorten life of water-using appliances. Long time of drinking hard water may easily make people more susceptible to all kinds of stone disease.
