Ever since Smart Air founder Thomas made his first DIY purifier, Smart Air has been telling the world that purifiers are needlessly overpriced. And ridiculously expensive replacement HEPA and carbon filters are one reason why.
HEPA filters were invented over 70 years ago by the US government. There’s no patent, nothing fancy – they’re just simple, effective tech.
Why then are replacement air purifier filters so expensive?
One more reason is margins. Other purifiers might throw in gimmicks, a marketing markup or middlemen which all inflate the costs. Smart Air does none of this.
That’s why the Blast can put out three times the clean air as that Swiss-made IQ Air and cost about 10% the price. Clean air is simple.
If you scale this up to 10 purifiers and the replacement filters needed for 3 years (what a typical 500-1000sqm office might need) then the comparison gets even more apparent.
Taking into account the cost of the machines, replacement filters, and power use, you’d save a whopping 86% of your money choosing the Blast Mini and all its replacement HEPA filters over the IQAir – all the while delivering MORE clean air. Looking at the Blue Air as another example, you’d save 58% of your money whilst breathing safer in the process.
Understanding the simple science behind purifiers nets substantial savings!
What if you’ve already got air purifiers in your space?
Let’s face it, some air purifiers are expensive to buy. If you’ve sunk your costs into a Blue Air or IQAir, you’d be reluctant to switch. However one smart organisation did the math, and worked out they could still save by choosing the Blast and Blast Mini…
How Smart Air Saved The BBC $25,000 on air purifiers
The BBC Beijing office was already equipped with IQAir’s when they called Smart Air. They were re-renovating their office, and so used the time wisely to re-evaluate their clean air options. They figured out the cost of replacement IQAir filters alone was much higher than switching to the Blast and Blast Mini, meaning they could save a huge amount in the process.
Here’s the calculation the BBC did in their head: over 3 years, how long will it take me to save money if I switch to the Blast and Blast Mini? The BBC took the cost of a new Blast Mini and all its replacement filters into account, and compared it to the costs of replacement IQAir filters.
The answer: After just 20 months, buying brand-new Blast Mini air purifiers is actually cheaper than sticking with IQAirs!
Bottom line: Even if you already have air purifiers in your office or home, the data shows that the over-priced replacement filters mean they’re still more expensive than switching to more cost-effective options in the long run.
To sum up, whether you’ve got air purifiers already or not, the Blasts are the smart, data-driven choice. Start breathing simple, effective clean air where you are starting with a free indoor air audit for your office!
