They come in different types, including inlet filters, water filters, and chemical filters, each designed to tackle specific types of pollutants.

Frequently Asked Questions (FAQs)
1. Do I need a filter for my pressure washer?
Yes, it is essential to have a good quality water filter installed on the inlet side of the pump for all pressure washers. Water naturally contains minerals, iron, dirt, rust, and other contaminants that can harm the pump. A filter helps prevent these contaminants from entering the pressure washer and ensures cleaner water is used.
2. What micron filter should I use for my pressure washer?
For the final filter, it is recommended to use a 5-micron filter. This finer filter improves water clarity, reduces abrasion on the pressure washer pump and unloader, and helps prolong their lifespan. Using a 5-micron filter also helps avoid warranty issues.
3. Can I use 5w30 instead of 10w30 in my pressure washer?
Generally, SAE 5w-30 or SAE 10w-30 are suitable grades of oil for pressure washers. However, it is always best to consult your owner's manual for the specific oil recommendation for your pressure washer.
4. What are the disadvantages of pressure filters?
One disadvantage of pressure filters is that the state of the filter bed cannot be directly observed during backwashing or when the filter is in operation. This can make it challenging to monitor and assess the filter's performance.
5. Can a dirty filter affect water pressure?
Yes, a dirty filter can restrict water flow and result in low water pressure. As the filter becomes clogged, water takes longer to pass through the filtering stage, leading to reduced water pressure and flow.
6. Which is better, a 5-micron or 30-micron filter?
The smaller the micron rating, the finer the particles the filter can remove. If you need to filter out smaller particles, a 5-micron filter is better as it can remove particles as small as 5 microns. A 30-micron filter will allow smaller particles to pass through its pores.
7. What grade of oil should I use in my pressure washer?
Common oil options for pressure washers are SAE 10W-30 and SAE 10W-40. However, it is recommended to consult your pressure washer's owner's manual for the manufacturer's specific oil recommendation.
8. What happens if I use SAE 30 instead of 10w30?
It is not recommended to use SAE 30 oil instead of 10W30 in a pressure washer. SAE 30 oil can cause larger engines to overheat, malfunction, or sustain permanent damage due to its properties.
