My Buying Guide on ‘Countertop Ro System With Water Tank On The Side’
I recently purchased a countertop RO system with a water tank on the side for my home and I have to say, it has made a huge difference in the quality of my drinking water. If you are in the market for a similar system, here are some key factors to consider before making your purchase.
1. Space and Size
The first thing to consider is the space available in your kitchen or wherever you plan on placing the RO system. Measure the area and make sure that the countertop RO system you choose will fit comfortably without taking up too much space. Keep in mind that some systems may be bulkier than others, so choose one that fits your needs and available space.
2. Capacity
The size of the water tank on the side will determine how much purified water you can have readily available at all times. Consider how much water your household consumes on a daily basis and choose a tank size accordingly. You don’t want to constantly refill the tank, but at the same time, you don’t want a tank that is too large for your needs.
3. Filtration Process
RO systems use different filtration processes to remove impurities from tap water. Some use multiple stages of filtration including sediment, carbon, and reverse osmosis membranes, while others may only have one or two stages. Look for systems with multiple stages of filtration as they are more effective in removing contaminants from your drinking water.
4. Maintenance and Replacement Filters
Like any other appliance, countertop RO systems require regular maintenance and replacement of filters to ensure optimal functioning. Before making a purchase, research how often filters need to be replaced and how easy it is to find replacement filters for your specific model. This will save you time and money in the long run.
5. Additional Features
Some countertop RO systems come with additional features such as a built-in TDS (total dissolved solids) monitor or pH balancing capabilities. These features can be beneficial if you are concerned about specific contaminants in your drinking water or if you prefer alkaline drinking water.
6. Budget
Countertop RO systems come in various price ranges, so it’s important to set a budget before starting your search. Keep in mind that cheaper models may not have as many features or may not be as durable as more expensive ones, so choose wisely based on your budget and needs.
