You should start by looking at the capacity. 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. Normally, the small families can use a storage capacity of 4-7 litres while the bigger families can use the storage capacity of 10 litres. Another thing is that we have some automated water purifiers which can detect when the volume of water goes down and refill it. When you do this perfectly you will be in a better position to select one of the convenient water purifiers.
Another factor that you should consider is if the water purifier is electric or non-electric. This is important as those people who live in places with constant power interruption should purchase water purifiers that can operate 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. Another thing is that electric purifies tend to be more efficient in purifying water than the non-electric purifiers.
Apart from that, you should also consider maintenance and after sales service. Generally, all the equipment needs maintenance besides water purifies. And without it the water purifier will not function as required. Once you bought the purifiers it is important that the dealers provide you with free or affordable after sales services which will make sure that you enjoy using the water purifier. You should also know that the cost of maintaining an electric water purifier is much higher than non-electric.
In addition, you should also consider installation and a warrant. You find that there are some companies that will provide you with free installation services. You find that there are some companies that will charge you a lot of money in installation. Apart from that, you should also check warranty which will allow you to use the purifier for some time and return it when it is not functioning well.
Lastly, you should also check ratings and the reviews. It is important that you go for highly rated water purifies as they tend to be effective in task execution. 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. You will be in a position to identify the best water purifier by looking at the one with many positive reviews as it always shows happy clients who are comfortable with the product.
