Whole house filters are used to treat water running in the entire home, so they are connected to the water mains that supplies the house such that all the water dispensed in the house (bathroom, kitchen, faucets, toilets, and laundry,) is treated. Usually, this type of filter is attached to the water mains before the supply line divides to the water heater. If you want to treat water to the sprinkler systems for the garden, then it may be a bit of a challenge. This is because the main water supply that comes off the city system divides into two lines – the house line and the yard line – in the foundation. The water utility may have further details about this, so consult them.
What Type Of Whole House Filter Should You Buy?
The type of whole house filter to buy depends on the type of impurities you want to get rid of from the water. The usual impurities in water from the municipal city supply include chemicals (such as chlorine), hardness minerals, and sediment. On the other hand, you’ll find impurities such as hardness minerals, iron, and sediment in water from a private well. The impurities generally range from harmless annoyances to potentially dangerous toxic materials.
If you’re using a private well for your water supply, just present a copy of your latest water analysis to EvoClear or let us test your water so that we can recommend appropriately based on the impurities discovered in the well water. If you get water from the municipal supply utility, then they should be able to provide you with a water analysis when you request for one.
Based on the water analysis report, EvoClear will recommend either filtration or softening. Water softening entails removing hardness minerals from water whereas filtration entails elimination of a broader range of impurities.
Types Of Common Impurities In Water
Chemicals – Chemicals are some of the most common impurities in water. In fact, all municipal water suppliers contain chlorine, a chemical used to disinfect water. Chlorine can be eliminated using a carbon filter.
Sediment – Sediment basically refers to visible impurities in water such as particles of dust, dirt, rust, and sand, among others. These particles are removed from water using mechanical means. Usually, they are simply strained out. If a water supply is laden too much sediment, then it would require several stages of filtration with every subsequent stage gradually getting finer. Water supplies that have less amount of sediment should consider using disposable filters.
Iron – Water supplies typically contain two types of iron – ferrous and ferric iron. Ferrous iron is dissolved in the water and therefore not visible while ferric iron is visible rust that may give water a red-brownish color.
What To Consider When Buying Whole House Filters
Filter size – Larger filters have longer service intervals, in addition to increased water pressure as well as volume. However, pressure and flow rate (gallons per meter or gpm) are greatly affected by port size. For most homes, the ideal filter size is 4.5-inch by 20-inch, however, a flow rate of 25 gpm and a larger port may be required for larger homes.
Flow Rate – The flow rate determines the amount of water that is distributed to the heater, toilet, shower, and dishwasher, among others. Flow rate is measured in gallons per meter and when determining the appropriate rate for your purification system, use the demand ratings advised on your appliances as well as toilet. On average, a shower head has a rating of 2.5 to 5 gpm; a toilet is rated 5 gpm; while a dishwasher is rated at 3gpm.
On average, most homes need water flow rates between 15 and 40 gpm, depending on how big a family is. However, regardless of family size, a whole house purification system with flow rate of less than 10 gpm is insufficient for maintaining comfortable pressure during heavy usage.
Port size – A whole house filter should ideally be 1-inch as it will not have any restrictions even when used with a piping system of ¾-inch. A 1-ich ported whole house system has enough water pressure to guarantee sustained supply during peak times.
