HRV - HEPA - Humidification
(HRV & ERV) - -
What is an HRV and or ERV?
An HRV is a heat recovery ventilator; it removes stale air and excess humidity from your home and replaces it with fresh air. An ERV is an Energy Recovery Ventilator, which removes less humidity than an HRV.
How does it work?
When fresh air is drawn into the one side of the heat exchange core, stale air is being drawn through the other side of the core by using a dedicated exhaust/stale air fan located inside the system. The fresh air is drawn in at the same airflow rate as the stale air is exhausted. As the stale and fresh air pass through on opposite sides of the core, the energy from the indoor air is transferred to the incoming fresh air and transferred to the living space. This occurs when the outdoor air temperature is either higher or lower than the indoor air temperature. The fresh air is then transferred to every room that has supply air registers within your home. The stale air is drawn from the bathrooms, kitchen and other moist air areas within your home. Since a constant negative pressure is caused at the bathroom, kitchen and moist air areas, no odours will transfer to the rest of the house.
Why should I get one installed?
When homes are built these day’s they are built more air tight, and already existing homes have undergone adjustments such as upgraded insulation, improved air sealing, new windows, doors, heating systems etc. an HRV/ERV should be installed when no air is transferring through out your home this causing stale air in your home which is very harmful for your everyday living. An HRV/ERV circulates the air in your home and transfers all the stale air and replaces it with fresh air.
Some typical household Pollutants
You can eliminate or reduce certain sources of indoor air pollution by understanding where household pollutants come from. However, no matter how careful you are, there will always be some pollutants in your home and, therefore, a need for ventilation.
Common Pollutants and their sources
Maintaining the unit
There are two filters in this system and they need to be checked and cleaned every three six months or when they appear dirty. To clean them you remove then from the unit and vacuum or they can be washed in warm water. The filters should be replaced yearly. The core of the unit needs to cleaned annually or as needed; to clean you use a soft brush attachment and or a soap and water solution.
HEPA Filtration Systems
What is a Hepa system?
A Hepa Filtration system filtrates the air you breath in your home
How does it work?
The air in your home is circulated through a 3 stage pre filter:
Why should I buy a Hepa System:
There are a lot of people who are concerned about the water they drink, so that is why more people these days are buying bottled water or a water filtration system.
People need to also start to worry about the air they breathe, it is found that the air in your home is 50 times more polluted then the air outside. In your home there are between 1 million and 2 million particles per cubic foot of air most of which is dust, pollen, car exhaust and other environmental pollutants. The average adult breathes in the equivalent of 1-2 teaspoons particulates every day. A Hepa filtration system works best for people who have breathing problems or have allergies. Many allergies are caused by exposure to airborne allergens including pollen and fungus spores. It also works great for people who have smokers in the house.
The Hepa filter eliminates 99.97% of the sub microscopic airborne particulates and even more of the larger particulates such as pet dander and dust mite feces. The Hepa system removes particles as small as .3 microns.
Where is it installed?
A Hepa system can be installed on a forced air furnace or it can be attached to your Air Handler in the attic for people who have the Lo-Velo or SpacePak system. Should your home use a radiant heat source a basic air distribution system can be installed which will be very effective.
Aprilaire fully automatic central humidifiers are simple and unobtrusive, safely and permanently installed in your laundry room in just a few hours. Up to 12 gallons of moisture per day, adjusted by you at the remote humidistat, will help relieve dry skin, nose bleeds, eliminate static shocks and static cling, and protect your fine furniture and art . . at a very reasonable price!
What is an Aprilaire humidifier?
The Aprilaire "350" is an automatic, self-filling central humidification system, perfect for homes without ducts. It is permanently installed by our professional servicemen, connects to existing plumbing and is powered by a normal wall outlet. You never need to fill it, empty it, or clean it!
Why is it so much better than a portable unit?
NO FILLING! The unit connects to the hot water supply, using an approved plumbing connection and a reliable shut-off valve. No more lugging pails of water! Because it is automatically controlled, it can be left on while you are away, protecting valuable furniture, musical instruments, plants, woodwork, etc.
NO CLEANING! Minerals and residue are washed down the drain! It requires only a yearly replacement of the water panel and minor service.
NO WHITE POWDER! It will not leave white powder on your furniture or in your lungs! Powder is an unfortunate byproduct of older ultrasonic portable units which "atomize" water into the air, where evaporation then takes place. Because the Aprilaire unit evaporates water inside the unit, mineral residue is washed down the drain before it has a chance to enter the air stream.
NO BACTERIA, NO ODOUR, NO SLIME! Unlike most drum-type portables, there is no pool of stagnant water in the bottom, therefore, no place for bacteria to breed, no slimy residue and no foul odours.
HIGH CAPACITY! The Aprilaire unit can disperse up to 12 gallons of moisture per day, a capacity up to six times greater than portable units.
How does it work?
Just set the humidistat (similar to a thermostat) at the humidity level you wish to maintain; the system then turns on and off automatically to maintain humidity at that level. When the air in your suite becomes to dry, a solenoid valve opens to allow hot water to flow through a patented "evaporation panel," through which air is drawn. This moist air is then sent through a short section of flexible duct (usually hidden above your ceiling) to an unobtrusive white grille in a ceiling or wall nearby. From there, humidity automatically distributes itself evenly throughout the entire suite.
How will it humidify my entire home?
Humidity travels evenly according to a scientific principle called "Dalton's Law of Partial Pressures" which states: "In a gaseous mixture, the molecules of each gas are evenly dispersed throughout the entire volume of the mixture." Have you ever burned a piece of toast in the kitchen and noticed how quickly the smell spreads throughout the entire suite? That is proof because the same principle applies to humidity! We are so confident in this natural law that we guarantee its effectiveness!
