As the technology as evolved we are witnessing a change in
each and every piece of equipment we use. Modern refrigerators are coming up
with facilities of ice making and water dispensing. Water dispensing directly
from refrigerator is cool idea for people who like to have chilled water
instantly. Refrigerators having these facilities are more likely to have water
filter unit. Water filter units are
having two types of models based on their working principle i.e. inline filters
and canister filters. No matter whatever type of filter it is, it requires
replacement timely. So the question what arises here that what is the right
time to change my refrigerator filter unit? But before getting to the answer to
this question let’s first understand how the filter unit works.
Refrigerator water filter unit uses carbon filters for
removing the contamination of tap water supply. It blocks the various harmful
elements like lead, mercury, chlorine, VOCs and other sediments. Now coming
back to our question that is, what is the right time to change the refrigeratorfilter?
Filter units have a normal life span of 5-6 months depending
on the use of the unit. The easiest of knowing the right time for replacement
is when filter status light alerts that it is the time for replacement. Whereas
no matter what type of refrigerator you are using, whether status lights are
present or not it is always recommended to change the filter unit within a
period of six months. Six months is just the norm, however the right time
certainly depends on the use of the unit. Some people are having the tendency
of changing the filters once the water starts becoming unbearable. However this
is not a good practice as it causes an undue pressure on the refrigerator.
Another way of knowing is when the flow of water starts decreasing. This is an
indication that the water has start clogging within the filters and now is the
right time to change it.
And before going for a change one should always look for a
NSF certification of the new filter. NSF certification determines that whether
or not, the new filter is going to be effective. Before considering a new filter one should
always check the compatibility of the filter with your model of refrigerator as
there are numerous of filters present in the market. So my advice to you is
that you fix a date which you can remember like a holiday or someone’s birthday
and go for a check on the filters six months past that date.
