Overview of Humidex and EZ Breathe
Humidex is a central ventilation and humidity control system designed and manufactured in Canada.
It works by constantly circulating air in the home and exchanging stale, humid indoor air with fresh air from outside.
The system uses an air-to-air heat exchanger core to temper the incoming fresh air so that comfortable humidity levels are maintained without drastic temperature changes.
Humidex systems include humidity sensors, motorized dampers, and variable speed blowers controlled by a wall-mounted digital controller.
Humidex claims to reduce humidity levels by up to 50% relative to outside levels.
EZ Breathe is a whole house ventilation system manufactured in the United States that utilizes the principle of air-to-air heat exchange like the Humidex. It works by expelling stale indoor air out while simultaneously bringing fresh air in.
The EZ Breathe system includes a heat recovery ventilator (HRV) or energy recovery ventilator (ERV) along with ductwork, grilles, diffusers and an air filtration system. The system is controlled via a digital wall control panel. EZ Breathe claims to improve indoor air quality and balance humidity.
Key Differences Between Humidex And EZ Breathe Ventilation System
- Humidity Control and Ventilation Performance
Controlling excess moisture and humidity is one of the main purposes of both Humidex and EZ Breathe systems.
Humidex leverages multi-speed blowers and motorized dampers to monitor humidity levels and exchange air accordingly to maintain an ideal 40-60% humidity range. The variable speed motors adjust operation based on conditions to avoid under or over ventilating.
Humidex’s proprietary humidity tracking technology is programmed to run the system just enough to control humidity, while conserving energy. Most users report 50-70% reductions in relative humidity during summer months.
EZ Breathe systems rely on the air filtration and HRV/ERV technology to exchange air and balance humidity levels. The ERV core helps remove moisture while preventing expensive conditioned air from escaping, giving it an advantage over simpler exhaust fans.
EZ Breathe claims to typically maintain indoor humidity around 50%. However, the ventilation rate is not adjusted automatically based on changing conditions like with the Humidex. The EZ Breathe system must be set manually based on seasonal changes.
Most impartial reviews and user reports suggest the Humidex provides superior humidity control and ventilation performance overall compared to EZ breath systems. Humidex’s active monitoring and variable operation means it can respond to changing conditions for optimal moisture removal and air exchange.
- Ease of Installation
Installing any whole house ventilation system requires appropriate HVAC expertise.
Licensed contractors are recommended for both Humidex and EZ Breathe installation.
Humidex systems are designed for straightforward installation.
All components including the air-to-air exchanger core, controls, and ducting come pre-assembled as a package for convenient mounting.
Humidex provides detailed product diagrams and install manuals. Complete installation takes around 8-12 hours.
The system works with any furnace or air handler and existing ductwork in most cases.
EZ Breathe systems involve more extensive installation which must be carefully planned. The contractor must design and install all needed ductwork, registers, HRV/ERV core, air filters, and control panel.
Configurations can vary greatly for different home layouts. The entire installation process typically takes 16 hours or longer. Ductwork must be sized precisely using specialized software for optimal airflow and performance.
Overall, the plug-and-play design of the Humidex makes installation quicker, easier and less labor intensive compared to the intricate ductwork and design of EZ Breathe systems. This can also translate to lower installation costs.
- Energy Efficiency and Cost Savings
Energy efficiency is another important consideration when choosing any ventilation system. You want maximum moisture control and air exchange without driving up energy bills.
Humidex uses a high-efficiency counterflow heat exchanger core to recover up to 80% of heating or cooling energy from exhausted air. This conserves energy usage while providing continuous fresh air ventilation.
Humidex’s variable speed blowers also operate on demand, further optimizing energy efficiency. Overall, most users report 15-30% reductions in annual HVAC costs after installing a Humidex system.
EZ Breathe also recovers some energy via its ERV or HRV core. However, most models only achieve 60-70% heat recovery efficiency.
And because the system runs at a constant rate rather than adjusting to demand, over-ventilation can occur which undermines energy savings. Energy costs decreases are typically less significant compared to Humidex, around 8-15%.
Clearly, the Humidex offers superior energy efficiency and cost savings for homeowners. You get the maximum moisture removal and air exchange with minimal impact on energy consumption.
- Noise Levels
Excessive noise from ventilation fans and blowers is another common concern. No one wants their system disturbing their peace and quiet.
Humidex systems emit very low noise levels around 35 – 45 decibels on the lowest fan speed setting. Even at higher speeds, the sound is comparable to a quiet bathroom exhaust fan. This minimal noise means the system can run 24/7 without irritation.
The variable speed motors adjust smoothly across fan speeds without excessive cyclic noise.
EZ Breathe units also operate quietly at around 45 – 55 decibels. However, some users note the constant air movement sounds from ductwork and diffusers takes getting used to.
And because the system doesn’t adjust speeds like Humidex based on demand, there is less flexibility to reduce noise during peak times.
Overall, the Humidex again rates favorably in terms of running silently to maintain your desired environment. The variable fan speeds allow matching sound levels to usage and occupancy patterns in your home.
- Maintenance Requirements
Low maintenance is an important benefit for any home system. You want a set-it-and-forget-it experience as much as possible.
Humidex systems include MERV 13 filters that only need replacement every 12-15 months. This provides excellent dust and allergen control with minimal maintenance needs.
If the filter becomes excessively dirty, the system will indicate a warning on the digital display. Beyond an annual filter swap, the Humidex requires no other regular maintenance when installed correctly.
EZ Breathe maintenance involves replacing filters every 3-6 months depending on usage. Higher grade MERV 13 filters can restrict airflow, so less effective MERV 8 filters are commonly used.
Users may also need to periodically clean HRV/ERV cores and ductwork for maximum performance. There is generally more hands-on maintenance involved with the EZ Breathe system.
The superior filter design and lack of duct cleaning required gives the Humidex an advantage in terms of minimal maintenance for the homeowner.
- Costs and Warranty
Installed cost and long-term warranty coverage are other key factors to weigh when selecting a home ventilation system.
A complete Humidex system installed by a contractor averages $3000 to $4000 depending on the model and home size. Humidex provides a comprehensive limited lifetime warranty covering the main system components, core, and electronics against defects. Only filters and peripheral parts are excluded.
EZ Breathe systems have a higher installed cost, averaging $4000 – $6000+ varying by model and house design. The parts and labor warranty provided is more limited at just 5 years for defects. The warranty is shorter and excludes filters, ducting and other wear items.
Considering the higher upfront cost, shorter warranty period, and higher maintenance costs of filters, the Humidex is arguably the better value proposition for most homeowners’ budgets.
- Smart Home Integration
Modern homes demand seamless smart home integration and control. You want to monitor and adjust your ventilation system conveniently.
Humidex systems can integrate with most standard smart home platforms like Google Home, Amazon Alexa and Apple HomeKit via the Humidex Smart Control accessory. This allows hands-free voice control and automation based on home occupancy and environmental factors for greater convenience and efficiency.
Currently EZ Breathe does not offer smart home integration or remote accessibility. The included wall control panel allows basic system monitoring and adjustments at home only. Those desiring whole house ventilation with smart features will prefer the Humidex.
Frequently Asked Questions (FAQ)
Yes, a Humidex system is generally superior to a stand-alone dehumidifier for whole home humidity control. Humidex actively monitors and adjusts operation to maintain ideal humidity levels between 40-60% RH.
