I was recently reading WHO and BIS guidelines, water with TDS levels below 500 ppm is considered safe for drinking. This means you usually don’t need a RO purification system. So unless your water comes from areas close to industrial sites, you can choose non-electric water purifiers. In cases where the TDS levels are around 250 ppm or less, gravity-based water purifiers should work just fine.
Kent Gold Optima Gravity Water Purifier:
I’ve discovered that using this purifier has some great advantages. It comes with straightforward technology, operates without electricity, and has a clear water tank. Plus, it effectively eliminates contaminants as minuscule as 0.1 microns, which is highly impressive.
On the downside, I’ve noticed a few drawbacks. The 5L capacity is quite limited, and I’ve found myself frequently needing to replace the filters. Additionally, it requires regular cleaning to maintain its efficiency.
Tata Swach Steel Gravity Water Purifier:
Tata Swach Steel Gravity Water Purifier operates without electricity, which I found particularly convenient. It’s specifically suitable for Indian cities that receive RO-purified water through their taps, making it an ideal fit. So if you live in such a place, then you can go for it. Moreover, it’s durable, low-maintenance, and impressively avoids wasting water, a standout feature.
It has a few downsides during my use. It’s not advisable for water with high TDS levels, which limits its applicability. Additionally, refilling the tank involves manual operations, and the opaque body makes it somewhat challenging to keep track of water levels, requiring more attention.
Prestige Non-Electric Acrylic Water Purifier:
Based on my personal usage, I’ve found several positives about this water purification system. The transparent body makes it effortless to monitor water levels, and its auto cut-off float system effectively prevents any overflow issues. It also offers a decent capacity suitable for meeting the needs of a medium-sized family.
I’ve experienced a few drawbacks during my usage. I noticed that it requires frequent cleaning and filter replacements, which can be a bit inconvenient. Moreover, it’s not recommended for water with TDS levels exceeding 200 ppm, limiting its effectiveness in certain situations. Additionally, the filters are less durable compared to stainless steel alternatives.
Tata Swach Cristella Advance Blue Water Purifier:
This is another purifier that works on gravity-based operation and ensures a continuous supply of clean water round the clock, which I found incredibly convenient. With a 9L capacity, it adequately meets the needs of medium-sized Indian families. Installation and usage are straightforward, making it user-friendly. Additionally, its unique design adds an attractive touch to the appliance.
However, I did come across a couple of downsides during my usage. The tap design could use some improvement for better functionality. Also, the purification process takes approximately two to three hours to produce just one liter of purified water, which might be a bit time-consuming at times.
Brita Marella XL:
This one operates on batteries. Its high portability was another positive aspect I appreciated. Additionally, the electronic Brita Memo serves as a useful reminder for filter cartridge replacements, adding to its user-friendly features. Moreover, its design is quite appealing and adds an exciting touch to the product.
However, I did encounter a couple of downsides during my usage. It’s not recommended for water with TDS levels surpassing 250 ppm, limiting its suitability for certain water sources. Also, the necessity for monthly filter replacements was a bit more frequent than expected, requiring more frequent maintenance.
Final thoughts:
I’ve learned that if the water source has TDS levels below 500 ppm, there’s no need for RO water purification. Similarly, when bacterial contamination is minimal, I found that UV purification isn’t essential. In these situations, I’ve found that gravity-based water purifiers offer the best solution for clean water.
