Problems solved by technology

However, the washing mesh has large pores and thus mainly filters large-sized dust and hair
Therefore, the filtering effect is poor
Small coarse mesh filters also have a poor filtering effect due to the small filter size
In addition, small coarse mesh filters cannot be applied to different types of air conditioners

Embodiment

[0043] In order to verify the effect of coverage on the fan speed of the air conditioner, a GWH12KF-D3DNB1C / I split air conditioner manufactured by GREE was used for testing. The Gree air conditioner is provided with two plastic washing nets with the same size at the inlet end of the cooling coil, and the size of each washing net is 27.3cm×29.8cm. Seventeen nonwoven filter material samples made of different materials were evaluated for their effect on the fan speed of a Gree air conditioner. Three different air filter coverage levels were tested for each of the seventeen nonwoven filter material samples: 100%, 68%, and 83%. For the tests performed at 68% coverage, the wash was wrapped with the air filter, leaving a distance of 2.54 cm between each edge of the filter material sample and the edge of the wash web to achieve 68% coverage. For tests performed at 83% coverage, the wash was wrapped with the air filter, leaving a distance of 2.54 cm between each edge of the filter ma...

Abstract

Some embodiments of the present disclosure relate to improving or overcoming at least one problem in existing air filters by including at least one folding structure in or on the air filter. The folding structure is capable of being bent to enable the air filter to be wrapped around or secured to a, for example, washing net. The folding structure can also hold the air filter securely to the, for example, washing net.

Description

technical field [0001] The present invention generally relates to air filters. In some embodiments, the air filter is used in an air conditioner, air filter, or air moving device. In some embodiments, air filters are used in domestic air conditioners. Background technique [0002] Air pollution has become a global problem. Especially in places like China, air quality is and will continue to be a chronic problem. As people's living standards improve, people expect higher air quality. In order to remove indoor air pollutants, washing nets are often arranged in indoor air conditioning units. Some air conditioners have small coarse-mesh filters in the wash screen. However, the washing mesh has large pores and thus primarily filters large-sized dust and hair. Therefore, the filtering effect is poor. Small coarse mesh filters also have a poor filtering effect due to the small filter size. In addition, small coarse mesh filters cannot be applied to different types of air co...
