Capacity is one of the factors that will guide you in choosing the best purifier. You find that most of the purifiers come with storage tanks to store purified water. The number of people that will be willing to use the purified water for drinking will greatly determine the capacity of the storage tank you go for. Talking of capacity you find that people with small families can be well served with a storage capacity of at least 4 litres unlike large families which needs a storage capacity of 10 litres. It is better if you go for automated water purifiers which will detect when the level of water goes down in the tank and refill it. This is important as it will prevent you from purchasing a wrong water purifier.
Another factor that you should consider is if the water purifier is electric or non-electric. You find that places with constant power interruption are not fit with electric water purifiers but they need the ones that can operate even without electricity. Such places can be well served with gravity based water purifiers since they don’t need electrify to operate. Not only that but their maintenance cost is also not that high. The difference will be efficiency as electric water purifies tend to do it faster and more perfect than non-electric water purifiers.
Another thing that you should consider is maintenance and after sales service. Maintenance is very essential in all the equipment not only water purifiers. This is important as it will ensure that the water purifier serves you well as required. Normally, the supplies of the water purifiers always provide you with free or affordable after sales service. You should also know that the cost of maintaining an electric water purifier is much higher than non-electric.
Another thing that you should consider is installation and a warranty. One thing that you can do is to buy with the companies that will not charge you any fee in installation of water purifier. You find that there are some companies that will charge you a lot of money in installation. Another thing is a warranty which will allow you to use water purifier for a given period of time and return if it is not functioning well.
Apart from that, you should also check warranty and the ratings. For high quality water it is important that you select the water purifier that is highly rated amongst others. In addition, you should also consider online reviews as they will give you chance to go through some of the customers comments about different types of water purifiers. The best water purifier should be the one with many positive comments as this shows that the people are satisfied with that particular product.
