The air filter removes contaminants from the air drawn in by the engine, allowing it to maintain proper engine power, torque, and fuel consumption. Without the filter, contaminated air containing pollen and street dust would enter the combustion chamber. Impurities in the engine operate like abrasive paper, causing damage to piston rings, bushes, and cylinders.

A battery separator is membrane placed between the positively charged anode and the negatively charged cathode. This configuration helps prevent electrical short circuits.

A good oil filter has a strong burst-resistant steel canister, a flexible anti-drainback valve that allows it to avoid back-pressure and leakage at cold temperatures, a bypass valve that does not weep at normal operating pressures (causing bypass), and a strong filter element with supported pleats and endcaps/seam that are sealed tight.

Filter efficiency, resistance to airflow, and dust-holding capacity are all factors in proper filter selection and performance. The filter's efficiency is measured by its capacity to remove particles from the air stream. For most filters and applications, the most important attribute is minimum efficiency over the life of the filter.

Reverse Osmosis membrane is a method used to remove the majority of pollutants from water by forcing the water through a semi-permeable membrane under high pressure. It is the most cost-effective approach for eliminating up to 99 percent of pollutants from feed water. It is a technology of percentage rejection. Therefore, the resulting product water depends on the quality of the incoming water.

Polyester wallpaper It is thicker than ordinary wallpaper and can be put to walls with defects or damage. It can be placed in damp locations, such as the bathroom, because to its resistance to water. Regarding its installation, the adhesive is applied directly to the wall, which saves a significant deal of time because a tapestry table is not required to apply the adhesive first.

Microfiber nonwoven fabric is cut into face shape, it becomes micro-fiber mask sheet. The microfiber mask sheet is made of ultra-fine synthetic fiber from the polyester. Micro-fiber mask sheets cannot be degraded. It is thicker & lighter than cotton and feels like soft silk. It is breathable & kind to the skin.
