Why Are HEPA Filters so Expensive?

When you are using an air purifier, you will notice that the HEPA filters involved are extremely expensive. High Efficiency Particulate Air (HEPA) filters can remove as much as 99% of airborne particles and microbes from the air. This also includes allergens, smoke, and mold spores. These devices will vastly improve the air quality of your home and your overall quality of life. Just like most of these finer things in life, these HEPA filters will cost you a pretty penny. This blog will explain the economics and science that make HEPA filters so expensive to constantly replace.

How Technology Affects Price of HEPA Filters

HEPA air filters have a very complex technology. They are made up of woven fibers. In fact, they trap and keep 99% of airborne microbes and particles. This can include anything from pet hair and seasonal dander that causes allergies, as well as tobacco smoke. The process goes through three steps: Interception, impaction and diffusion. Along the process of purification, these three steps ensure that the microbes are either trapped or negated from circulating in your air space.

The material that makes up these filters is usually woven fiberglass that are engineered specially for interception of these tiny molecules. Whether you are filtering your home or professional space, you can count on HEPA filters to clear the air.

How Longevity Affects Price of HEPA Filters

The lifespan of your HEPA filter depends on the quality. Some filters are washable and can last for a long time, sometimes up to five years. Read descriptions, reviews, and instruction manuals to plan whether you will have to budget out filters consistently or if your filter is washable. Some HEPA filters are actually permanent and there is no possibility to wash or replace them. This means that you will have to vacuum them using a hose.

How Purifier Size Affects Price of HEPA Filters

Bigger HEPA filters will clean more air space, but they will also be more expensive. With purifiers on the market offering various different space coverage, it is important to know your needs before shopping. If you are cleaning large, corporate, or industrial spaces, you will need a large, heavy duty HEPA filter. It is important to know that it could cost much more than traditional filters. If you are simply going room to room in your house, the size of your machine will be much smaller and in line with consumer prices.

How Purifier Brand Affects Price of HEPA Filters

Brands matter because the quality of your product and customer service experience starts and ends with the company’s reputation and commitment to excellence. To design and produce great products while also giving a great warranty and customer service, companies will have to charge more. Don’t settle for filters that are not backed by a strong brand or manufacturer warranty. In case you do, you will quickly have to replace it when it fails to finish the job or breaks. Read reviews, check the website and social media, and do as much research as you can to protect your investment.

My new recertified Sirena

I am so thrilled with my recertified Sirena. I am absolutely shocked with how pristine my recertified purchase is! This vacuum looks and runs, like a new machine! It's in perfect working order. I was so fed up with machines that had no suction. I swore that no matter what I had to do I would find a machine that worked! I was nervous to buy online, but many years ago my mother had a water filtration unit & absolutely swore it was the best. Even though I could not be sure, I decided to buy one through the recertified option. I felt I could deal with a nick or two if it meant I got a machine with good suction. Well, I didn't get good, I got great! The machine is much quieter than I thought it would be, and I love the suction power. It really works!! I will admit that it is a bit more effort to properly make sure you empty the water and store main unit with out water reservoir, but the job it's doing is amazing. I feel like crying over all the money I wasted having to repeatedly buy new machines, but I won't cause I'm so happy now. Oh, and watch the videos! They are super helpful if you have a question! Worth every penny I paid this time! 😆

Love it!

When I was younger my mom had the Rainbow vacuum and that’s when I was exposed to the water vacuum but now being an adult with my own family and allergies I wanted a vacuum that worked well like when I was a child however a rainbow is much more expensive! When I got my Sirena I was impressed at how comparable it is to the rainbow for half the cost if not more! Our air felt cleaner, the amount of dirt it picked up was amazing! I’m very pleased so far!
