What is HEPA?
HEPA - High Efficiency Particulate Arresting
HEPA filter is over 99.9 % efficient in trapping all allergens and airborne
contaminates down to 0.3 micron in size such as: lung damaging dust, mold
spores, plant spores, pet dander, pollen, bird feather dust, dust mite debris,
bacteria, germs, microbes, etc. 30 Particles at 0.3 micron in size out of
100,000 ones pass through the HEPA filter (on average).
What is negative ion?
The Negative ion can be generated when- hydrodioxgen
(water) is impacted to form negative oxygen ion; or in ionization, the needle
can discharge dissociative electron when it is under a high negative voltage.
The electron can easily combined with mutual oxygen and form negative oxygen
ion. The breath becomes much cozy and relax when we are near water falls, at sea
beaches, or in mountains. This is because there are more negative oxygen ions at
such places. The negative oxygen ion is also called as “air vitamin”. It helps
to improve the air quality, and also helps to eliminate efficiently the
irritating gases released from decoration material such as benzene, formaldehyde
and ammonia etc. It can also have reactions with odor molecules attached on the
wall and ceiling. The same time, it also has an effect to prevent the growth of
mold and germs.
General Effects on Health
Research has shown that negative ions can do the following:
- Reduce histamine, which triggers hay fever.
- Affect levels of serotonin, a neuro hormone associated
with anxiety, stress and migraine.
- Have a beneficial effect on anyone suffering from
bronchial complaints such as bronchitis asthma, catarrh and the common cold.
- Help sufferers of insomnia, migraine, emphysema, eczema,
headaches, tiredness, and general feelings of malaise.
- Increase the speed and quality of healing of burns and
surgical incisions with less cross infection and reduced pain.
- Enhance the body’s absorption and utilization of oxygen,
thus assisting concentration and alertness.
- Reduce the effects of passive smoking ,and allergies to
pollen, dust and pets.
- Remove and destroy airborne bacteria and viruses.
- Anion’s working principle, biological effects and
physical effects
- Biological effects of air anion
1. Adjust the stimulation and inhibiting action of the central
Nerve Anion, Alveolus→blood→Blood brain barrier→Cerebrospinal fluid →Central
nervous system
2. Improve the lung’s ventilation functions, Anion→respiratory tract mucosa,
promote the motivation of the mucosa cilium, gland exudation ↑,smooth muscle
excitability↑, ventilation↑
3. Reduce the blood pressure Anion→monoamine oxidase (MAO) →oxidative
deaminization →the concentration of 5-HT,eatecholamine and noradrenalin ↓reduce
the blood pressure
4. Stimulate the hemopoiesis, normalize the blood ingredient, Anion→blood,
enhance the erythrocyte’s repulsion→slow down the ESR.
Anion→ Splinic function ↑, Erythrocyte &blood calcium ↑.
5. Accelerate the histiocyte biological oxidation-reduction.
6. Anti-virus, promote the immunologic function.
· Oxygen anion (superoxide anion freeradical) has high bioactivity, which play
an important role in sterilization.
· Anion give the epithelial cell negative electric charge which will increase
the repulsion to the anions with the same charge and deprive the virus’ attack
ability to the cells.
· Anion can promote the Iymphopoiesis and elevate the content of igA, igM,
alexin and interferon.
What is ozone?
Ozone is highly reactive, and oxidizes pollutants it encounters,
rendering them harmless, while also removing odors.
The function of ozone is basically to enable production of hydroxyl radicals,
and to help oxidize odors, bacteria, mold, chemicals, and many other pollutants.
How does ozone work? Ozone oxidizes airborne
pollutants, then reverts to oxygen, leaving behind cleansed and refresh Ned air.
Oxygen Molecules Ozone Molecules converted from oxygen (right) as a result of an
electrical charge, such as that provided by lightning, or an IPS air purifier.
One oxygen atom splits off to oxidize pollutant, leaving behind breathable
oxygen and purified air. Ozone is highly reactive, so it interacts with most
contaminates and allergens it encounters. As the element with the second highest
oxidation potential (next to flourine), ozone proceeds to destroy the pollutant
through oxidation.
What is “Relative Humidity”?
Relative humidity is the percentage of the actual water vapor contains
to the saturated water vapor contains under the same definite temperature and
space. We normally mark it with “%RH”, like 45%RH. Atmospheric air always
contains water vapor. The percentage of which depends on the meteorological
conditions. The higher the temperature is the more water vapor the air can keep.
Therefore, we use the concept of “relative humidity”.
When the cold air is heated up to a comfort room temperature by heating systems
in winter, the relative percentage of the water vapor contains in the air falls
down, which means the relative humidity drops. Now you feel the air is “dry”. In
order to keep a comfortable and healthy environment at home, we need some
artificial help to add water, or, water vapor, to the room air- that’s air
humidification.
Ideal relative humidity level under different situation
·The most comfortable RH for human body: 45-65%RH
· Ideal RH for prophylactic and curative purpose: 40-55%RH
· Computer and telecom apparatuses: 45-60%RH
· Furniture and musical instrument: 40-60%RH
· Libraries (books), art galleries and museums: 40-60%RH
Why indoor air quality is important to our health?
Air is one of the basic factors for all living creatures in the
world. Statistically, an adult breaths over 20’000 time during one day which is
13 to 15 kilogram of air. This is 10 times the weight of food, or three times of
water an adult need during one day. The quality of the breathing air has a close
and direct relation with people’s living standard and health.
In modern life, over 90% of your time is spent indoors (such as at home, in
offices or public buildings etc.), and the quality of indoor air is 5 to 10
times over polluted than the outdoor air. Bacteria, germs, dusts, acarid,
nicotine, poison and harmful gases released slowly from construction and
decoration materials such as formaldehyde, ammonia. All these floating
components in the air harms the health of human being. Symptoms like premature
senility, insomnia, and amnesia are frequently found; the worse cases will even
lead to asthma, heart and lung prostration, or other vital disease.
Indoor air pollution has been listed by the World Health Organization as one of
the top ten factors that harm human lives.
