Which is the Best Water Purifier Without RO Technology?

When choosing a water purifier without Reverse Osmosis (RO) technology, it's essential to understand the different purification methods and the specific needs of your household. Several non-RO options, such as UV, activated carbon filters, and gravity-based systems, are available to address various water quality concerns effectively.

UV Water Purifiers

UV water purifiers utilize ultraviolet (UV) light to eliminate bacteria and viruses, providing clean drinking water. These systems are popular among those seeking a compact and efficient solution for small households. Some notable UV purifiers include:

Pureit Classic UV Water Purifier: This purifier is renowned for its effective UV purification process, making it suitable for small households. Kent Ultra UV Water Purifier: This model not only employs UV technology but also comes equipped with a carbon filter to enhance taste and remove odors.

Activated Carbon Filters

Activated carbon filters are another effective option for improving the taste and removing contaminants from tap water. They are popular due to their simplicity and effectiveness. Some well-known branded activated carbon filters are:

Brita Water Filter Pitcher: This is a widely popular choice for improving the taste and eliminating contaminants from tap water. Aquagear Water Filter Pitcher: Designed to remove lead, chlorine, and other harmful substances, this pitcher is ideal for daily drinking water needs.

Gravity-Based Purifiers

Gravity-based purifiers are known for their user-friendly design, requiring no electricity. These systems use a combination of filtration methods such as candle filters or nanotechnology to purify water. Some popular gravity-based purifiers are:

Tata Swach: This model utilizes a combination of a candle filter and silver nanotechnology for effective water purification. HUL Pureit Eco Water Saver: This purifier is designed for non-electric operation and uses a combination of activated carbon and UV light.

Key Factors to Consider When Choosing a Non-RO Purifier

While choosing a non-RO water purifier, several key factors should be considered:

Contaminants: Determine the specific contaminants present in your water supply. Different purifiers are better suited for different types of impurities. Capacity: Select a model that matches your household size and daily water consumption requirements. Maintenance: Consider the ease of filter replacement and overall maintenance. Certifications: Look for products certified by relevant health and safety organizations to ensure their efficacy.

When RO Technology is Required

Reverse Osmosis (RO) technology is necessary when using water directly from its source, such as borewells, tankers, and rivers. This is especially crucial for areas heavily polluted by industrial waste, containing contaminants like arsenic, lead, and fluoride.

In contrast, municipal water undergoes advanced purification processes at water treatment plants, making additional filtration at home unnecessary. Non-RO purifiers are typically used for municipal water to remove dust, pathogens, and suspended particles introduced during transportation through water pipelines.

Types of Non-RO Water Purifiers in the Market

Non-RO purifiers available in the market include:

UF (Ultrafiltration) and NF (Nano-filtration) UV Water Purifiers: These purifiers are suitable for water with TDS levels between 250-500 PPM and 150-300 PPM respectively. Gravity-Based Water Purifiers: These are ideal for water with TDS below 150 PPM.

By considering these factors and understanding the specific needs of your household, you can choose the best non-RO water purifier to ensure clean and safe drinking water.
