I've got a Samsung refrigerator with an ice maker and water dispenser, and I'm not sure if I'm replacing the filter often enough. The manual says every 6 months, but some people online say they go a year or more without issues. What's actually recommended to keep the water clean and safe?
Samsung's 6-month recommendation is the safest bet - it accounts for varying water quality in different areas, and filters do get less effective over time even if the water still tastes okay. People stretching them longer might be fine if they have really clean tap water, but you're gambling with sediment and contaminants building up, and it's cheap insurance to just swap it twice a year.
