General Water Filters Buying Guide- How to chose a suitable water filter?
After reading all sorts of different water filters on the existing market, which filter should be most suitable for your needs?
A wise choice of water filter could supply the house with clean water for years. But nearly all of them are required to replace filters after a period of use. Once you had made the decision of investing in a particular model of water filter in the marketplace, do go through the following list to double check if that model is the best one in your circumstances. If you have no idea which model to acquire yet, this list would be your water filter buying guide.
Identify your needs before shopping
If you only care about improving the taste and odour of drinking water, water dispensers and faucet water filters could fit the job. On the other hand if you would also like to remove impurities from tap water, you may need a reverse osmosis water filtering system. If your household water comes from a private well, reverse osmosis water filter is a must for removing contaminants like nitrates and arsenic. Run some tests on tap water if you are not sure whether or not it contains a high percentage of impurities. It would not be surprising to discover lead and copper from tap water, because they usually leach and travel in municipal water pipes to your home plumbing units. As little amount of impurities it seems, you also have to consider the aftermath of long term intake of impurities into family members’ body. So if you have the budget, investing on reverse osmosis water filter is the safest solution, especially for dwellings with kids, maternity and elderly, or families which depend on drinking and cooking at home.
Keep notes on the following for selecting a water filter:
Only obtain water filters certified by NSF
Never trust all the information provided by the manufacturers and peddlers, take them for references only. Do look for certified products registered by independent testing organization such as NSF international and Water Quality Association (WQA). We recommend customers only buy water filters which are certified by NSF. But NSF has various certification standards, do check out which ones should you be going for instead of randomly picking one which have the label of NSF.
Compare filtration power according to your needs
The more impurities the filtered water is, the more expensive is the water filter generally. Cheaper filtering treatments like water pitchers and dispensers could only eliminate bad odour and improve the taste of tap water, while reverse osmosis water filter could also remove molecular contaminants apart from that.
Buy water filters with warranty
Only obtain water filters which come with warranty. If you are getting reverse osmosis water filter system, go for a model which gives you as least 2-3 years of warranty. As you are investing on the most complicated model which has to be installed under sink, it sounds rational for the warranty to cover a longer period of duration.
Manufactured company and brand
All kinds of water filters have the needs for their filters to be replaced after time, and replacement filters and water filters are usually manufactured by the same company. So if you want to keep your water treatment system lasts as long as you need, select one which is financially stable enough so that replacement filters are available in the marketplace as long as you are still using their water filters. This is more convenient when they are there for support if any problems arise. Given today’s fluctuate economy, there are chances that giants could collapse, so better obtain a model which are used by most people and buy from a manufactured company which has a long history of making water filters. The market of water filters are not as volatile as the mobile phone market, manufacturers would release new models once a while, but they would try to make replacement filters compatible for a wide range of their products, so, give less worries for the discontinuation of replacement water filters.
The lifetime of filter replacement
Sediment filters absorb impurities, and they have to be replaced after a while when the old ones are saturated. Certainly the longer the filter lasts the better. The lifetime of water filters range from one month to 18 months.
The cost of replacing filters and installation of water filters
Filters of water pitchers and faucet mount water filters could be easily installed and replaced manually. But if the water filter is installed under sink, plumbing knowledge is necessary for installer, or you might have to hire a plumber to do the job. Many reverse osmosis water filter models are installed under sink, but there are also some models mounted on faucets. It really depends if you want the water filter to be out of view or not.
Filter replacement indicator
Some filters was equipped with a lighting signal to indicate the need of filter replacement. Consult the sales if the signal is only a theoretical indicator like count down timer or if it really gives out accurate replacement signal based on consumption or saturation of the existing filters. But even if the replacement signal is not included, filters usually have to be replaced when a significant decrease of water flow is detected from the faucet. So it does not matter much if an replacement indicator comes in the package or not, it is just a good-to-have, but not necessary.
