Our Pearl hard water filter is a high performance drinking water filter system that improves the taste and odour of your water, removes chlorine and sediments and reduces it's hardness.
This hard water filter effectively prevents limescale and rust build up in your household appliances such as kettles, coffee machines, taps, electric showers, water heaters and many other types of cold water processing equipment.
How hard is my water? In the north and west of the UK the water is naturally soft, wheras, in the south and east it is naturally hard. Approximately 60% of houses in the UK have hard water.
The Pearl hard water filter is suitable for under sink or counter top mounting.
The housing dimensions are 34H x 14W x 13D (volume occupied in cm).
It's the dissolved minerals in hard water that gives it the following characteristics:
The minerals that contribute to water hardness are calcium and magnesium, mainly in combination with bicarbonate, sulphate and chloride. When hard water is heated above 61° (or as it evaporates) the balance between the dissolved minerals is upset and the bicarbonate converts to carbonate. This is where you get the calcium carbonate scale (limescale).
Hardness in water is measured in mg/l or ppm (parts per million) of calcium carbonate equivalent (the main component of limescale). The word equivalent is used to show that it is not calcium carbonate that is being measured (it cannot be as calcium carbonate is not present in water) but that the amount of different hardness minerals present in the water is chemically equivalent to an amount of calcium carbonate.
Classification | hardness in mg/L | hardness in mmol/L | hardness in dGH/°dH | hardness in gpg | hardness in ppm |
Soft | 0-60 | 0-0.60 | 0-3.37 | 0-3.50 | less than 60 |
Moderately hard | 61-120 | 0.61-1.20 | 3.38-6.74 | 3.56-7.01 | 60-120 |
Hard | 121-180 | 1.21-1.80 | 6.75-10.11 | 7.06-10.51 | 120-180 |
Very Hard | >181 | >1.81 | >10.12 | >10.57 | >181 |
