When it comes to keeping your pool clean and clear, not all chlorine is created equal. While both American-made and Chinese chlorine may contain similar active ingredients, the way they are manufactured can significantly affect their performance, longevity, and even safety. In this article, we'll break down the key differences so you can make an informed choice for your pool.


Manufacturing Quality Matters
One of the biggest distinctions between chlorine made in the US and Chinese chlorine is the production process. Chlorine tablets require precise compression to ensure they dissolve at a controlled rate and provide consistent sanitation.
- Doheny’s American-Made Chlorine: Our chlorine is meticulously manufactured using precise heat and pressure to form dense, durable tablets. This results in a longer-lasting product that dissolves evenly and consistently, ensuring optimal pool sanitation without waste.
- Chinese Chlorine: Many Chinese-produced chlorine tablets are not as well-compressed, leading to faster dissolution and inconsistent chlorine release. This means you'll need to use more chlorine over time to maintain proper water balance.
Purity & Fillers
The purity of chlorine tablets can also impact their effectiveness.
- Doheny’s American-Made Chlorine: Our tablets are 99% pure, with no unnecessary fillers. This ensures that every tablet delivers the highest level of sanitation without adding unwanted substances to your pool.
- Chinese Chlorine: While some Chinese chlorine tablets may claim similar ingredients, they often contain more fillers, which lead to residue buildup and less effective chlorination.
Storage & Stability Concerns
Another critical factor to consider is how chlorine affects its surroundings when stored.
- Doheny’s American-Made Chlorine: Our chlorine tablets emit significantly fewer fumes, thanks to their superior compression and purity. This means they are safer to store without worrying about damaging nearby metal objects or creating a harsh, unpleasant odor.
- Chinese Chlorine: Because these tablets are often less dense and contain more impurities, they release more corrosive fumes. Over time, these fumes can damage storage containers, metal shelving, and even nearby pool equipment, leading to unnecessary costs and potential safety concerns.
