Abduction, squatting, burying, turning, deceiving—these are not just words. They describe the real situation of people being misled by substandard water purifiers. What happened to the body of the water purifier? It's a question many consumers ask after seeing their expensive units fail or not perform as expected.
Today, it's common to see low-cost water purifiers being sold at "cabbage prices." Many buyers don't understand why branded models cost so much. But what really makes these cheap purifiers so affordable? The answer lies in their core components—or rather, the lack thereof.
The heart of any water purifier is its filter element. This is the main part that removes impurities from your water. To determine if a brand is reliable, you should first look at the quality of its filters. A high-quality filter can cost hundreds of dollars, which might seem like a lot for an average household. That’s why some people wonder: Is there a water purifier that doesn’t require changing the filter?
Is there a water purifier that doesn’t need a filter replacement?
The short answer is no. All water purifiers require filter replacements over time. Some products on the market may claim to last up to five years, but these claims are often exaggerated. In reality, the lifespan of each filter depends on the type and usage conditions.
Most household water purifiers use RO (reverse osmosis) membranes, ultrafiltration membranes, PP cotton filters, and activated carbon filters. The PP cotton and activated carbon filters typically need to be replaced every 3 to 6 months, while the RO or ultrafiltration membranes can last 2 to 3 years. However, this timeline can vary based on water quality and how often the unit is used.
Why do water purifiers need filter replacements?
Filters work by trapping impurities from the water. Over time, these impurities accumulate and cannot be fully rinsed away. If left unchanged, they can clog the system and reduce efficiency. In fact, a purifier that becomes clogged is actually doing its job well—it’s effectively filtering out contaminants. So, regular maintenance is essential for safe and clean water.
So, is there a water purifier that never needs a filter change? The answer is no. But that doesn’t mean you should avoid buying one. Water purifiers are an investment in your health, and a good filter is worth the cost. After all, you wouldn’t want to drink polluted water just to save a few dollars.
The dangers of cheap filters
Many low-cost water purifiers on the market use substandard filters. These may be made with poor materials, cut corners, or even contain harmful substances. For example, some use coal-based activated carbon instead of high-quality coconut shell carbon. This type of carbon has lower adsorption capacity and may not meet safety standards. In some cases, it can even release harmful chemicals into your water.
PP cotton filters are also often compromised. Low-quality versions may have fewer grams of material, leading to poor filtration in the first stage. This allows more pollutants to pass through and damage the subsequent filters. As a result, the entire system can become contaminated, leading to "secondary pollution." Long-term exposure to such water can seriously harm your family’s health.
When it comes to your health, it's better to invest in a reliable water purifier with quality filters. Your source of life—your drinking water—deserves the best care possible. Don’t compromise on something as important as clean water.
