Frost-free Freezers

Frost-free freezers are now almost a defacto standard in most refrigerators used at home. Ever wondered how they work compared to the old frosted type freezers? It’s quite simple actually, all it contains is an auto timer which heats your freezer section to “melt the ice” at fixed intervals. It just replaces the defrost button in the old freezers. It does come with the advantage that you don’t need to clean the frost as in old freezers but there is no free lunch here.

Frost-free freezers are much more power-hungry than the old type of freezers because of the regular heat cycling to remove the frost. So it will add to your monthly electricity bill. The temperature inside that won’t be as cool as the older ones. So things won’t last that long if you want to keep it in there.

If you are looking for the most power-efficient freezers out there for long-term use, pick the ones which are used in shops for cooling icecreams, meat etc. The ones with the top door open type. They are built in such a way to minimize the heat loss(Top door) as cool air sinks and keeps things cooler.

Things you learn when you simply start observing things in and around your home.

Planned Product Obsolescence of a Water Purifier

People who use Aquaguard or any water purifier in their homes find the common issue of a stable green indicator light(or whatever colour according to your model) which is a so-called LED to tell you to change your filter cartridge. In most of these models please understand that this light has nothing to do with a measured quality/life of a filter. It’s just an electronic timer which counts the time and turns on this light. Please don’t get fooled by this.

The way to reset this is, to open the back panel of your filter and find a small reset switch. Keep it pressed on while the power is on for around 30secs or so to reset the light. Then it will be back to normal. This is just kept there to get you to buy new filters from the company. The famous “Recurring Revenue model”.

To calculate the time to change your filter, just measure your daily water consumption from the purifier and calculate the number of days it will run for. A good cartridge is slated for at least 6000L of water purification(It would be mentioned on the cartridge). Please make informed decisions on facts and don’t get fooled by the planned obsolescence tactics by companies.
