The TATA Swach Steel Gravity Water Purifier brings back memories of the old days when RO and UV/UF water purifiers were not so common in India.
Almost every Indian home had a gravity water purifier that used two sediment filter candles to trap impurities and other contaminants to deliver sufficiently pure water. The TATA Swach Steel Gravity water purifier is a modern-day version of the gravity water filters of the yesteryears.
Pros of TATA Swach Steel Gravity Water Purifier
- This product does not need electricity to work, like the present-day RO purifiers.
- It is ideal for the municipality supply water sources that are usually RO-treated.
- The stainless steel body lasts long and makes the product durable.
- This product does not waste any water like the RO water purifiers.
Cons of TATA Swach Steel Gravity Water Purifier
- This water purifier is not recommended for purifying water with TDS levels of more than 250ppm.
- The manual operations require you to watch the water levels at all times to ensure pure water availability.
- Though TATA claims the filter has a capacity of 20L, it is 10L of pure water at any time.
Our Opinion
The TATA Swach Gravity water purifier is suitable for homes relying on RO-purified water supplied by municipalities in many cities. This water purifier is better than the gravity water filters of the olden days because it has an activated carbon filter to cater to aromatic impurities and improve the water’s taste.
While TATA claims that its cartridge can filter up to 6000 liters of water, our experience shows that much depends on the quality of the water source.
Besides. TATA claims that this product can handle TDS levels of up to 1500ppm. But the reality is different. We have experienced that this product is ideal for TDS levels up to 250ppm.
Another disadvantage is that you cannot add water to the top tank if the bottom container is full. The water will overflow.
However, the TATA Swach Gravity water purifier is a good product because it delivers good performance and lasts long without much maintenance.
Design
The TATA Swach Gravity water purifier comprises two stainless steel water tanks placed one over the other. The water filter cartridge is present in the top tank. Both tanks have an equal water-holding capacity of ten liters.
The 10L pure water capacity should be sufficient for small and medium Indian families. However, manual operations can discourage people from preferring this water purifier. But this water purifier offers a direct tap fill option, but it is not automatic.
TATA claims the water purification rate is between four to five liters per hour. But, the disadvantage is that you cannot fill the upper tank unless you empty the lower tank. Otherwise, the water will overflow. In addition, there is no automatic shut-off option in this appliance.
The appliance has a detachable water tap fixed to the lower tank for water dispensation.
Performance
The performance of the TATA Swach Gravity water purifier is satisfactory, especially if you have a water source with TDS levels of less than 250ppm. Anything more than that, and the water purifier will not be helpful. However, TATA claims it can handle TDS levels up to 1500ppm.
The TATA Swach Gravity water purifier has a two-stage water purification system comprising sediment and carbon filters. The filter cartridge can last up to 6000 liters and work with water in the pH range of 5.5 to 9.
While the filter cartridge can last up to 6000 liters, there is no way to know whether it has become ineffective or crossed its expiry date. The appliance does not have any sensors to indicate the time for replacing the cartridge.
TATA claims that this product satisfies the LRV for bacteria, viruses, and cysts according to USEPA guidelines. In addition, the anti-biofouling feature removes sediment residue from the cartridges and lengthens their lifespan.
