There‘s no doubt that maintaining healthy, clean air inside your home is important for your family‘s wellbeing. In recent years, smart air purifiers have emerged as a high-tech solution, allowing you to monitor and control your air quality right from your smartphone. However, despite the allure of these Wi-Fi connected devices, there are several compelling reasons why you may want to think twice before rushing out to buy the latest smart air cleaner.
As someone passionate about digital technology, I‘m always eager to embrace devices that truly enhance our lives. But when it comes to smart air purifiers, I believe the drawbacks outweigh the benefits for most households. Here‘s a closer look at why you might want to avoid hopping on the smart air purifier bandwagon and stick with proven, lower-tech alternatives instead.
The first strike against smart air purifiers is the higher price tag compared to regular HEPA filter-based models. While connecting an air purifier to your home‘s Wi-Fi does provide the convenient ability to control it remotely and monitor your air quality from an app, in most cases it doesn‘t actually make the device clean the air any better. You‘re essentially paying a premium just for the smart functionality.
A quality air purifier without smart features can cost around $100-200 for a model suited for an average size room. But similar capacity smart air purifiers often run $300 or more. Paying double the price or higher for an app-connected model just doesn‘t make financial sense for the limited convenience it provides for most people.
Another factor to consider is that, like any smart device, a Wi-Fi enabled air purifier requires periodic software updates to function optimally and patch any security vulnerabilities. If you neglect to keep the firmware up-to-date, you could be left with a buggy device prone to malfunction or even hacking.
Even more concerning, if the manufacturer eventually decides to stop supporting a particular smart air purifier model, it may become impossible to update, rendering the smart functionality virtually useless if it becomes incompatible with newer smartphones. With a regular air purifier, you never have to worry about it becoming outdated or losing support.
Smart air purifiers‘ reliance on a steady Wi-Fi connection to operate properly is another potential downside. During internet outages, most smart air cleaners cannot be controlled at all. Some may continue to run but you lose the ability to change settings, set schedules or monitor air quality.
If your home frequently experiences connectivity issues, a smart air cleaner that requires an active Wi-Fi connection is probably not a wise investment. You‘re better off with a standard "dumb" model that cleans the air continuously regardless of your internet connection.
I‘m also not a fan of the way some smart air purifiers operate based on the air quality readings. While it may seem logical to have the purifier automatically kick into high gear when it detects elevated levels of airborne pollutants, this burst cleaning approach may ultimately be less effective than a regular air purifier that simply runs consistently to maintain optimally clean air 24/7.
If a smart air cleaner remains idle until air quality degrades to a certain level, it will have to work harder to remove the accumulated contaminants. This cycle of waiting until the air gets dirty and then frantically trying to clean it is less efficient than just keeping the air consistently clean with a constant flow of filtered air like a standard purifier does.
Another concern with certain smart (and non-smart) air cleaners is the use of ionizers to help trap airborne particulates. The problem is that ionizers can also produce ozone as a byproduct. While ozone is beneficial in the upper atmosphere for blocking UV rays, it‘s a lung irritant at ground level.
Even relatively low amounts of ozone can cause coughing, chest pain and shortness of breath. Some ionizer-equipped smart air purifiers can generate ozone levels exceeding 50 parts-per-billion, which is enough to be detrimental to your health over time with prolonged exposure. If you or anyone in your household has respiratory sensitivities, an ionizing air cleaner is best avoided altogether.
As with any internet-connected device, smart air purifiers also come with inherent privacy and security risks. While a hacker is unlikely to specifically target your air purifier, any smart device is a potential access point to infiltrate your home network. Once compromised, a hacker could potentially spy on you through the air purifier‘s app, access other devices on your network, or use it as part of a botnet for large scale cyber attacks.
There are also privacy concerns about the data smart air purifiers collect about your home environment and usage to ostensibly improve performance. But there‘s always a chance this data could be mishandled, hacked, or sold to third-parties for marketing purposes. Call me paranoid, but I personally don‘t feel comfortable sharing 24/7 data about the air quality inside my home with the corporation that made my air purifier.
Fortunately, there are highly effective, time-tested alternatives that provide all the air cleaning benefits of a smart air purifier without the connected complications and privacy risks. At the top of the list are standard HEPA air purifiers. These tried-and-true workhorses are as simple as it gets – just a fan that forces air through a High Efficiency Particulate Air (HEPA) filter capable of removing at least 99.97% of airborne particles down to 0.3 microns in size. This includes most allergens, dust, mold, bacteria and even some viruses.
Coupled with an activated charcoal pre-filter, a HEPA air purifier is all most households need to effectively and efficiently clean the air. Look for models with a Clean Air Delivery Rate (CADR) high enough for the size of the space and you‘re good to go. Many non-smart HEPA air purifiers today are extremely energy efficient and quiet, making them easy to run continuously for consistently clean air without sky high power bills or annoying background noise.
For a completely natural approach to cleaner indoor air, consider adding some houseplants, particularly those known for their air purifying abilities. Snake plants, spider plants, pothos, and many palms are great options that can filter out common household toxins like formaldehyde, benzene, and carbon monoxide – no electricity required! Not only do plants clean and oxygenate the air as part of photosynthesis, but the very presence of greenery and nature has also been shown to reduce stress, boost mood and enhance overall wellbeing. The more plants the better, but even just a few well-placed pots can make a noticeable difference in your home‘s air quality while also adding vibrant decor.
Another easy and inexpensive way to purify the air is with bamboo charcoal. Also known as activated charcoal, this highly porous substance is extremely effective at absorbing odors, humidity, and airborne toxins thanks to its massive surface area – a single gram can have upwards of 3000 square meters of microscopic pores and crevices! You can find bags of activated bamboo charcoal that work as a completely natural, chemical-free air purifier. Simply place them in areas prone to odors like bathrooms, closets, cars or near pet beds and litter boxes.
One of the great things about bamboo charcoal is how long it lasts – typically a full year or more. And when it eventually does get saturated, you don‘t toss it out. Instead, you simply place the charcoal outside in direct sunlight once a month for a couple hours to release the absorbed toxins and moisture, essentially resetting it so it‘s ready to keep purifying the air. With proper care, a bamboo charcoal air purifying bag can last up to two years, making it incredibly economical.
But what if you live somewhere that doesn‘t get reliable sunlight for rejuvenating your bamboo charcoal, like an apartment with limited natural light? Don‘t worry, there are a few easy alternative methods you can use to reactivate the charcoal, no sun required:
-
Oven: Preheat your oven to 300°F (150°C). Spread the charcoal out on a foil-lined baking sheet in a single layer. Bake for 1-2 hours, checking it every 30 minutes to avoid burning. Once the oil sheen has disappeared from the surface of the charcoal, it has released the absorbed moisture and pollutants, so it‘s ready to use again.
-
Boiling: Fill a large pot with enough water to entirely submerge your charcoal. Bring the water to a boil, then add the charcoal. Boil for 10-15 minutes, then drain and rinse with cool water. Spread the wet charcoal out on a towel in a well-ventilated area for 24-48 hours until completely dry.
-
Hair dryer: Put your charcoal in a large bowl. Hold a hair dryer 1-2 inches from the surface and move it slowly over the charcoal on high heat for about 10 minutes. Continue until the charcoal feels dry and any sheen is gone.
-
Microwave: Spread the charcoal out on a microwave-safe plate. Microwave on high in 1 minute intervals up to 3 minutes total, allowing it to cool for a minute between each zap. Use caution as the charcoal can get quite hot.
For a more eye-catching air purifying accent, try a Himalayan salt lamp. These striking lights consist of a large chunk of pink salt from the Himalayan mountains hollowed out to hold a small light bulb inside. When lit, they give off a soft, amber glow. But Himalayan salt lamps don‘t just look good, they‘re also believed to boost mood, reduce stress and improve sleep thanks to their natural red and orange hues that mimic the soothing colors of sunset.
They also emit beneficial negative ions which can help offset the effects of positive ions from electronics. But perhaps the coolest aspect of Himalayan salt lamps is their inherent hygroscopic nature, meaning they attract and retain water molecules from the surrounding environment. As the lamp warms up from the light inside, that trapped water evaporates back into the air, but any particulates like allergens, dust, pollen, smoke and bacteria remain bound to the salt.
So while a salt lamp won‘t filter the air like a HEPA purifier, it does act as a natural air cleanser at a microscopic level – all while providing soothing mood lighting and an eye-catching decor accent. Just remember that Himalayan salt lamps are best used in drier rooms like bedrooms and living rooms rather than humid bathrooms or kitchen environments, as excess moisture can speed up the dissolving of the salt itself over time.
So in summary, while smart air purifiers may seem appealing with their connected convenience, for most households the potential benefits don‘t justify the significantly higher cost, reliance on steady Wi-Fi, potential for outdated technology, and inherent cybersecurity risks compared to simpler and more affordable air cleaning solutions. A basic HEPA air purifier is still the gold standard for removing airborne contaminants and particulates. Houseplants offer a natural way to detoxify the air while enhancing your living space. Bamboo charcoal provides an electricity-free, highly economical odor and moisture absorber you can use anywhere. And Himalayan salt lamps harness the hygroscopic power of salt to trap pollutants while bathing your room in a soothing rosy glow.
Combined, these proven low-tech air purifying methods can help ensure the air in your home stays clean and healthy without the hassle and questionable necessity of adding yet another smart device that may only make life marginally better at best. Sometimes the simplest solution is still the smartest.
