When Should You Change RO Membranes and Filters?

There are so many water purifiers in the present world. Since the pollution is rising every passing day, the water is no longer safe to consume. You have to take precautions to ensure that the water you are consuming is clean, safe and hygienic. If you think that the local municipal authorities are taking care of water cleanliness then they are not doing it completely. They do take measures but their measures are not absolutely effective. You need to take precautions on your own to ensure water cleanliness.

You can use water purifiers or filtering systems at home. In this way you can ensure that your house is getting clean, safe and hygienic water.  You can get RO installation and it would be up and working for you right away. Certainly you cannot deny the fact that water is an essential consumption and nobody can stay alive without clean water. Similarly it is not just about water but safe water. What is the point if you are consuming dirty and unhygienic water? Similarly in case you are using an RO water purifier then you must know the significance of changing RO Membrane and Filters on time.

When talking about the maintenance of RO purifiers the foremost thing that comes to the minds is the replacement of the filters and membranes. It is necessary that you have a basic understanding of the episodic schedule of replacement of filters because filters and Membrane establish the major parts of any water purifier. And the price of replacement of filters and membrane is nearly eighty percent of total maintenance costs of an RO purifier.

The purpose of this post is not to make you a technical savvy on RO water purifiers but to give you a proper understanding of when to replace the filters and membrane of the water purifier you have. Such information would help in:

• Ensuring that you always get pure, clean and one hundred % safe water.
• Enhancing the life of your RO water purifier.
• Diminishing the maintenance cost.
• Evade being cheated by unethical service technicians.

The question at hand might seem to be very clear and quite straightforward but the answer is not that simple. It is because when you talk about replacing the filter and membrane the approach cannot be ‘one size that fits all’. Hence, before you get the light on details about when to replace RO membrane and filters, it is vital that you first get to know about all the factors on which it all relies. Below given factors should always be taken into consideration before estimating the great time to change RO membrane or filters.

• Degree of impurities in the input water.
• TDS Level or that of hardness of the input water.
• How much water do you purify using the RO purifier?

In case the water has extreme high level of impurities, high TDS level or in case you use your RO purifier to purify huge quantities of water, then the filters and RO membrane shall need to be replaced quite often. The schedule of change of RO membrane and filters that is given in the following paragraphs is for a general household of nearly four to six family members.

The RO pre-filter (installed outside the RO water purifier) has to ideally be replaced every three to four months. The replacement interval can be smaller or longer relying upon the quality and quantity of water purified. The other types of pre-filters that encompass the Sediment Filter and Carbon Filter should be changed every six to twelve months depending on how much water you purify and how bad or good the input water is. However, it is just an average and to get the exact time to change them you need to look at filters in an individual manner.

When to Change the Sediment filter?

Sediment Filter is specifically designed to eradicate sediment and dirt from the water so your carbon filter and RO membrane does not get stopped prematurely. Every residence might have different sum of sediment in the input water so there is no ‘one size fits all’ answer to tell you how long it shall last in your case.

It is vital to keep the pressure as high as possible going in to membrane and the sediment filter shall just cost a few hundred rupees.  It is always recommended to change the Sediment Filter on time. In case Sediment filter is not changed on time then the dirt or filth will reach the RO membrane and the membrane shall get blocked, this diminishes the efficiency and the life of RO Membrane. In case you maintain your Sediment Filter properly, the Carbon Filter and RO Membrane must last a long time. It is recommended that Sediment Filter should be changed minimum once a year.

When should you Change Carbon filter?

Water from Sediment Filter go through the carbon filter (also known as Activated Carbon Filter), it eradicates chlorine and other organic contaminants. Carbon filter even filters out the bad odour and unfriendly taste from the water.  Similarly Chlorine in water even adversely affects the life of the RO membrane. Activated carbon filter engrosses Chlorine and other organic impurities and thus extends the life of the RO membrane. It is hence very important to change the Carbon filter at regular intermissions in order to enhance the life of RO Membrane and avert bad odour and bad taste in purified water. Again it is recommended to replace your Carbon filter at least once in a year.

When to change RO membrane?

RO Membrane is the most important part of any RO water purifier. It is actually the filter that is doing all the tasks; the Sediment Filter and Carbon Filter just prepare the water for the RO membrane so it does not get harmed. The point is in case you take good care of sediment and carbon filters, and replace them at the needed intermissions then RO membrane just needs to be changed after purification of four thousand to six thousand litres of water.

Conclusion

Thus, since you know a lot about the procedures and needs of water purifier and their membranes; it is time that you take a decision for your RO water purifier. It is better to take precautions than to be regretful later on.
