How to Choose the Best RO Water Purifier?
Water Purifiers are necessary for every home because it provides safe and healthy drinking water at all times. It may be difficult to choose the best RO water purifiers in India considering the several models available.
Nevertheless, if you can conduct thorough research on the features and factors to consider when choosing the best RO water purifier for your home, then you’ll not fail in your purchase decision.
You can go through this complete buying guide in selecting the best RO water purifier in India.
- Quality of water
One of the most important factors to consider is the quality of water in your environment. This will determine the type of water purifier you may need in your home.
There are different kinds of filters and features available for all purifiers, meant for a specific purpose. But it’s helpful to know the quality of water first before purchasing a purifier. There are specific filters for hard or soft water, contaminated water, and water with TDS (Total Dissolved Solids).
TDS comprises organic substances in minute quantity and inorganic salts dissolved in water. If the water is hard with a high TDS level, it means that such water has a high salt content. Then, using the RO water purifier with a good filter is better. However, if the water is soft with low TDS, the best purification could be done with a multi-level carbon filter.
- Storage tank
Storage capacity is another critical factor in choosing the best RO water purifier in India. Some purifiers have a large storage tank that is suitable for a big family. The purification and storage capacity must be able to cater to your daily needs.
If the purification is for commercial purposes, it is necessary to purchase a purifier with adequate storage. In this case, a free-flowing water filter is perfect, though they have a low purification process. It is advisable to go for the one with good storage and a normal purification process.
An automatic purifier is a good option in that it filters water to the tank automatically, as soon as the water level goes down. This will give you a constant supply of water.
Selecting the best brand is an important factor to consider before purchasing the best RO water purifier in India. Most of the RO water purifiers has a good reputation and great customer feedback, while some are new brands.
It is better to choose a brand known for manufacturing good quality water purifiers with great reputation and feedback. Also, their certifications and brand symbols will help you make good decisions.
Water contains nitrate, suspended solids, and industrial waste, virus, bacteria, chemicals, and pesticides. These render the water harmful and dangerous to the body.
Contamination is lower in mountains but higher in rural areas and cities. If your water has a high level of contamination, then choose a purifier with UV+UF+RO, which has the highest ability to remove TDS from water. Also, for groundwater with sediments and bacteria, a multilevel carbon filter is better.
Some water purifiers are only meant for a particular type of contamination, so you must know the contamination in your water supply to decide the filters that are best for you.
- Maintenance / after-sales service
Regular maintenance is needed by this product periodically. The cartridge will need replacement at least once or twice in a year, and some filters require periodic maintenance of six months.
In this case, you must be sure that the after-sales service of the brand you purchase is active, thus making the maintenance more budget-friendly.
Also, go for brands with good customer support to lay complaints about the product easily.
Budget is one of the most important factors to consider while purchasing the best RO water purifier. Most people opt for their first water purifier in a low budget and neglect the important features to look for in the product.
However, it is not advisable to start with a more expensive model that you may not afford but never compromise on the price of filters and features. There are good models at a moderate price with all the essential features and great options.
- Certification and warranty
Ensure that you purchase a genuine and quality water filter by checking the certification of the product. Also, confirm the warranty of the purifier.
Now that you’re loaded with this information, let’s compare the different brands available to make a good choice of the Best RO Water Purifier in India.
