Purification capability

Air purification capabilities are an important factor when choosing the right negative ion generator. A negative ion generator, which can disperse plenty of negative ions throughout the room, has a high ability to remove dust and particles floating in the air. Purification capability Purification Capability - (Extract from "Pay attention to specifications") Specification item Example Importance Purification capability 90% of 0.3micron particles removed in 2 hours High Negative ions combine with dust and particles floating in the air and fall to the floor. As the result, the dust and particles no longer exist in the air. This is how the air is purified by negative ions. Air purification capabilities are an important factor when choosing the right negative ion generator. A negative ion generators, which can disperse plenty of negative ions throughout the room, has a high ability to remove dust and particles floating in the air. This figure shows how particles are removed to purify the air. [ Ion House just switched on ] - [ 1minute ] → [ 3minutes ] These photos show you cigarette smoke disappears (in 3 minutes). Air purification capabilities are an important factor when choosing the right product but manufacturers do not always provide this information.

Stable performance

Temperature and humidity changes can significantly lower the performance negative ion generators which employ the discharging method. You should choose a negative ion generator which is designed to maintain optimum performance under low/high temperature. Otherwise, it will not perform well under such conditions because the negative ion counts can dramatically drop. Stable performance Stable performance - (Extract from "Pay attention to specifications") Specification item Example Importance Stable performance Designed to maintain performance under extreme conditions Middle to High Temperature and humidity changes can significantly lower the performance negative ion generators which employ the discharging method. You should choose a negative ions generator which is designed to maintain optimum performance under low/high temperature. Otherwise, it will not perform well under such conditions because the negative ion counts can dramatically drop. This image shows you the Ion House maintains optimum performance under temperature and humidity changes. Very few products in the market are designed to maintain performance under extreme conditions.

Life span of ionizing needles

Negative ion generators which employ the discharging method can generate fewer negative ions than they are supposed to do or produce a lot of harmful ozone when the ionizing needles get worn out. Ionizing needles determine the life span of the ion generators. Life span of ionizing needles Life span of ionizing needles - (Extract from "Pay attention to specifications") Specification item Example Importance Life span of ionizing needles 5 years+ Middle The life spans of negative ion generators which employ the discharging method are usually determined by the ionizing needles. Ionizing needles gradually get worn out as a result of repetitive charging/discharging or by chemical reactions. Worn out needles can lower negative ion counts or produce a lot of harmful ozone. The life span of ionizing needles is an important factor because it determines the life span of the negative ion generator.

Positive ion count

Negative ion generators which employ the discharging method can generate both positive/negative ions simultaneously, which lowers negative ion counts because they are cancelled off by their positive counterparts. Positive ion count Positive ion count - (Extract from "Pay attention to specifications") Specification item Example Importance Positive ion counts 0(pcs/cc) Middle Negative ion generators can generate both positive/negative ions simultaneously, particularly if they employ the corona discharging method. Positive ion generation lowers negative ion counts because they are cancelled out by their positive counterparts. It is ideal not to produce positive ions.

Ozone production

Most of negative ion generators which employ the discharging method generate negative ions and ozone simultaneously. Highly concentrated ozone is harmful to the human body. You have to make sure that the product meets safety standards before you purchase it. Ozone production Ozone production - (Extract from "Pay attention to specifications") Specification item Example Importance Ozone production 0.001ppm or less Middle Most of negative ion generators which employ the discharging method generate negative ions and ozone simultaneously. Ozone gas is used for sterilizing/deodorant purposes but it is harmful to the human body if it is highly concentrated. The safety limit set by the Ministry of Health, Labour and Welfare is less than 0.1ppm (in working areas). Basically, a negative ion generator, which does not meet the safety standards, is not sold in the market. However, worn out ioznizing needles can generate highly concentrated ozone. Ozone itself has no odor but it can give off an offensive stimulating smell when it reacts with other substances in the air. You have to choose a product which meets safety standards and make sure if it does not give off the odor caused by the reaction if you do not like the smell.

Test operation

You cannot tell if your negative ion generator is working properly without an indicator light or a detector because you cannot see ions with the naked eye. Test operation Test operation - (Extract from "Pay attention to specifications") Specification item Example Importance Test operation Comes with the ion detector for test operation Middle You cannot tell if your negative ion generator is working properly because you cannot see ions with the naked eye. A negative ion generator which has a built-in indicator light and/or comes with a detector is ideal because they assure you that it is generating negative ions.

Maintenance

Maintenance procedures vary depending on the negative ion generator. You should know what maintenance work is required to maintain the performance before you purchase the generator. Maintenance Maintenance - (Extract from "Pay attention to specifications") Specification item Example Importance Maintenance Cleaning of the ionizing needles Middle Maintenance procedures vary depending on the negative ion generator. Some products require you to clean the ionizing needles or replace the filters on a regular basis, while those which generate negative ions by crashing water require you to clean/refill the water tanks. You should know what maintenance work is required to maintain the performance before you purchase the negative ion generator.
