INOVA Air Purifiers | INOVA Blog

If you are in the market for an air purifier, you’ve probably seen the word HEPA splashed across every box and website. It sounds like the gold standard—and in many ways, it is —but in the world of air purification, a single label can hide a massive difference in performance.

When shopping for an air purifier, one of the first things you’ll often see highlighted is the Clean Air Delivery Rate (CADR) — a number that supposedly tells you how effective a purifier is at cleaning the air. At first glance, it seems like a simple, objective way to compare products.

According to a recent ABC report, these tiny plastic particles are everywhere, including in our bodies and brains — and our own homes may be where exposure is highest. If you’re a homeowner (or responsible for indoor environments), this is a wake-up call: Even if you’re careful about dust, cleaning and ventilation, there’s a hidden pollutant conventional methods may not fully address. That’s where a high-quality air purifier from INOVA comes in.

All INOVA air purifiers are designed so that the airflow path has the activated carbon filter located after the HEPA filter. Here's why...

1. Protecting the Carbon from Dust and Particulate Loading
2. Extending Filter Lifespan and Reducing Maintenance Costs
3. Ensuring Proper Airflow and Pressure Management
4. Preventing Cross-Contamination and Secondary Emissions
5. Optimising for Gas Removal Efficiency
6. Common Design Order in Multi-Stage Systems

This order reflects decades of air filtration best practice in hospital cleanrooms, aircraft, and consumer purifiers.

For people living with CIRS, clean indoor air is a daily necessity. The winning formula is simple: stop the moisture, remove the damage, control humidity, and filter continuously with a sealed, medical-grade HEPA + deep-bed carbon purifier sized to your rooms. That’s the approach INOVA is built around.

It’s an incredibly common marketing model, especially in the world of consumer electronics and appliances. The problem isn’t that affiliate links exist — it’s that they create a powerful financial incentive for the reviewer to steer you toward certain brands or models.

When shopping for an air purifier, one of the most important components to consider is the HEPA (High-Efficiency Particulate Air) filter. It’s the part responsible for capturing the harmful particles we don’t want to breathe in—like dust, pollen, smoke, and even bacteria or viruses. But not all HEPA filters are created equal.

Did you know that a little mould in your bathroom corner or living room wall might be doing more than just smelling unpleasant or looking unsightly? Recent research from France shows that even the tiniest visible mould growth is associated with increased risk of asthma and worse asthma symptom control. 

As an air purifier company, INOVA is always on the lookout for fresh science that helps you breathe easier. That study reinforces why mould management is not just about upkeep—it’s a matter of lung health.

A recent landmark study from the University of Tasmania’s Centre for Safe Air,  the first peer-reviewed assessment on this scale,  revealed that traffic-related air pollution (TRAP), mainly fine particulate matter (PM) and nitrogen dioxide (NO₂), contributes to more than 1,800 premature deaths in Australia annually.
