![]() In our opinion Negative Air is the winner. The Rotary Brush method misses the goal of cleaning all the dust, debris and other contaminants from the home. Since the Rotary Brush uses no negative air pressure in the ventilation system, the dirt thrown can also escape into the home through seams in the ductwork. The larger particles may remain at the bottom of the vent after duct cleaning. The suction of the rotary brush vacuum picks up smaller particles, but is not strong enough to vacuum heavier objects. The spinning motion of the brush throws debris in every direction. Rotary Brush machines are equipt with a vacuum in the center of the brush. And, in addition to all of this, we even clean the vent covers for you! Negative air cleans the entire HVAC system. The heavy particles fall to the bottom of the ductwork and air scrubbing tools force them toward the vacuum. The Negative air machine sucks the light particles into the attached containers. We then use a camera and agitation tools to dislodge the contaminates found inside. ![]() We connect the negative air machine to the ductwork or plenum which puts it under negative pressure. How it worksĪt 4 Seasons we use the Negative Air. A Negative Air system cleans the trunklines and plenums whereas a Rotary brush system does not create any negative pressure and is unable to clean these areas. The plenums are the pieces that join your HVAC equipment and ductwork, allowing circulation between the two. Trunklines and plenumsĪ trunkline is a line of ducting that serves as the distribution source for your HVAC system. The 3 inch brushes of the Rotary Brush get caught in small ductwork. Smaller ductworkĪ Negative Air system handles sharp turns and smaller ductwork with ease because the air sweep and brush are smaller than an inch in diameter. A Rotary Brush system cannot pass through dampers. Negative Air machines are well equipt to work with dampers and they do not pose any issues. These dampers are often in zone control systems. Some homes have dampers which are moveable plates inside the ductwork which direct airflow to specific areas of the home. Negative Air systems remove not only dust, but also larger pieces of construction debris, plaster, rodents, and even toys! Rotary brush systems cannot collect larger pieces of debris due to small nozzle size. The more powerful Negative Air system removes far more dust, dander, pollen, mold, mildew. Below are the differences between the two: Vacuum strengthĪ Negative Air machine typically vacuums at 2000cfm whereas a Rotary brush system (Rotobrush, Ram Air, Goodway, Ductmaster, Rotovac) vacuums at 300cfm on the high end. ![]() Companies throughout the industry, however, practice both methods. ![]() The National Air Duct Cleaning Association ( NADCA) recognizes the Negative Air as the most comprehensive method. While both remove dust and other debris from your system, they differ in the results they achieve. Negative Air method (what we do) and Rotary brush method.

A pet might cough, sneeze, produce discharge from the eyes and/or nose, or suffer from vomiting, diarrhea, lethargy, or lack of appetite. When you first use them, a pet might immediately withdraw from the area or cower. Mahaney, the negative effects of air fresheners may appear immediately or within a few hours or days after use. “When you walk into a room that’s been heavily sprayed with air freshener, what does it do to your eyes and lungs? If it’s doing that to you, it’s also going to do that to your pets.” Signs of a Toxic Reaction to Air Fresheners in PetsĪccording to Dr. “Read the instructions on the side of the bottle and be sure you are spraying the recommended amount,” says Dr. When it comes to using these products around our pets, a little information is your best defense. “Also, birds are more sensitive to potential airborne toxins than are other animals, so I generally recommend a ‘better safe than sorry’ approach with the use of air fresheners around them.” ![]() Jennifer Coates of Fort Collins, Colorado. If you simply have to have essential oils in the home, make sure they are kept in a location where your pets cannot come into direct contact with them,” says veterinarian Dr. “Essential oils, which are included in many air freshener products, can be very toxic, especially to cats. Essential oils are also defined as volatile, and while these substances are extracted from flowers, bark, berries, roots, seeds, and woods, and do have some potential medicinal and positive effects, they can still be very toxic to people and animals, particularly when they are used improperly. For “green” products, emissions of these compounds were not significantly different from the other products.” Natural Alternatives to Air Fresheners: Are Essential Oils Safer?įor the air freshener industry, the latest catch phrase is “essential oils.” Despite this natural-sounding name, these products are by no means entirely safe. federal laws, and each product emitted at least one of these compounds. Of these 133 VOCs, 24 are classified as toxic or hazardous under U.S. Some VOCs can cause cancer in animals some are suspected or known to cause cancer in humans.Īnd in a study published in the Environmental Impact Assessment Review, testing of top selling air fresheners and laundry detergents “found 133 different VOCs emitted from the 25 products, with an average of 17 VOCs per product. Headaches, loss of coordination, lethargy and nauseaĭamage to liver, kidney and central nervous system According to the Environmental Protection Agency, the health effects of VOCs may include: These substances can cause a laundry list of maladies. You wouldn’t open a can of paint in your living room to improve the quality of the air, but this isn’t too far removed from what happens when you break out an air freshener. ![]() Unfortunately, this is the same volatility that occurs in paints and varnishes, fossil fuels, benzene, formaldehyde, refrigerants, aerosol propellants, cigarette smoke, and the dry-cleaning process. In other words, volatility is just how air fresheners are meant to behave: dissipate into the air, thereby changing its scent. This transformation is called volatility. This causes these compounds to easily turn into gasses or vapors from a solid or liquid form. VOCs are organic chemicals that have a high vapor pressure at room temperature. ![]() Mahaney, one of the main offenders in the ingredient list for most air fresheners are volatile organic compounds (VOC). The Ingredients That Makes Air Fresheners Dangerous for PetsĪccording to Dr. Sadly, some forms of air fresheners can be quite toxic, especially to animals (and children!) who might ingest the substances or not have the wherewithal to avoid parts of the home where they’ve been used. ![]() “If we are putting some kind of chemical into the air merely to mask scents, then we have to be concerned about the negative implications for our pets,” says holistic veterinarian Dr. However, there are some ways to play it safe when using these products in the home. So, do pet owners need to forever do away with their room sprays, plug-ins, candles, oils, and solids? That’s a question that’s not so easily answered. Some of the things we do to improve our environment, such as cleaning or using chemical air fresheners, can pose dangers to our animal friends, whether furry, feathered, or scaled. But unlike children, instead of this being a temporary obligation, it’s something we’ll need to do throughout the lives of our pets. Reviewed and updated for accuracy on by Jennifer Coates, DVMĪs parents and caregivers, one of the earliest lessons we learn is the concept of “baby-proofing”-keeping toxic substances and dangerous situations well out of the way of our children. ![]() Function declarations are not part of the regular top-to-bottom flow of control. The code works, even when the function is defined below the code ( function call ) that uses it. The parentheses themselves are always required for every function you defined ( irrespective of the way you define the function ) and they allow you to receive arguments that would be input to your function.Then we have curly braces, curly braces surround the function body and that is the code which executes when this function gets called.A function is created with an expression that starts with the keyword function.A complex problem is generally more managable when broken down into simpler subproblems. Then the program will be easier to understand and to update than the sequntial one. ![]() Functions allow us to reuse code and create different modules to perform some procedures we plan on using repeatedly (solution to the problem of code duplication).Functions allow us to repeat tasks that involve a similar sequence of steps (processing). They dont give away the entire solution, but rather try to help you find it yourself. A function is a group of statements that performs a particular task. Functions are a crucial concept in pretty much any programming language.

That’s why it’s so important to keep bringing our thoughts captive to the truth on a daily basis. And teach us to love others better or teach us to become even more self-absorbed than we already are. Those challenges can either draw us closer to God or further away from God. What I’m learning as I go through life is that each stage of life has its challenges. ![]() Which of course wasn’t enough to keep me happy. Instead of believing that life is about loving God and others, I was believing that life was about having fun.Īnd instead of relying on God when life wasn’t fun, in those days I relied on quick bursts of excitement from the refrigerator. Instead of believing that I should lay my life down out of love for the brethren (in this case, my kids), I was believing that I deserved the “good life.” And because I grew up in a culture that told me every day that I deserved the “good life,” I had picked up some lies that added to my discontent. ![]() What I’m trying to say is that I was spoiled. I loved my kids and we had many fun adventures together when the weather was nice.īut I live in the north, so there are weeks and weeks every winter where the weather isn’t conducive to being outside having fun. Not to mention the little fact that we had to do school each day. So when I became a stay-at-home mom 26 years ago and eventually a homeschool mom, I wasn’t really well-suited to the job. ![]() Newly created Allied Race characters will now be directed to Chromie, not the warboard.All Allied Races can now be unlocked once you have a level 40 character on your account (was level 50).All restrictions for unlocking Allied Races have been removed, with the exception of a level requirement.Grimoires can be learned on the PTR this week, but selecting the appearance of your pets in the Barbershop will be available in a future PTR update.
